How do you measure slope?
It is the derivative of the vertical change relative to the horizontal change - if the derivative exists. So, with the typical x-y graph, it would be dy/dx. If the graph is a straight line, then it is the change in the vertical positions between any two points divided by the change in the horizontal positions between the same two points (in the same order).
What 2 things are recommended in order for you to have a neat graph?
it mom
Which type of graph would be most appropriate to help you organize a set of data in numerical order?
Bar chart or bar graph
What conlusions can you draw if the line of best fit on a linear graph does not slope either up or down but its horizontal?
The independent variable is not linearly related by the independent variable over the domain. It does not mean that there is no relationship between the variables. For example, a quadratic relationship (y = ax2 + bx + c) over a domain that is symmetric about the vertex (-b/2a) will result in a horizontal line. Similar regions can be found for any polynomial of even order.
How do you draw a curve with straight lines?
While a curve is one continuous motion, you can create the illusion of a curve by using straight lines. In order to do this, draw a continuous pattern of short straight lines, while changing the direction of each line slightly.
How is order of reaction determined graphically?
in our syllabus there is only the first and the zero order reaction in which if the graph is plotted between the concentration and time then it is a zero order reaction while if the graph is between the log of concentration and time then the reaction is of the first order.hope this will help u.
How do you prove graphically that a reaction is first order?
If a reaction is first order, a graph of reaction rate against reagent concentration will be a straight line.
What is the energy profile of a chemical reaction including activation energy free energy change and transition state?
These are all pictured here, it is describing the energy state for a reaction. http://images.absoluteastronomy.com/images/encyclopediaimages/a/acactivation_energy.svg.png Free energy refers to the Gibbs energy for a reaction, this is what tells us if the reaction will take place. It is defined as the difference of energy (y-axis) between the initial and final. In order for the reaction to be spontaneous, the final energy state must be lower than the initial. Activation energy is the amount of energy that must be introduced into the system in order to begin the activation. On the graph, it is the peak. The graph does not have any transition species, but if did they would be denoted by other "hills" in the curve, between the activation and final states.

How does the distance versus time graph look for an object that is stopped?
You can use the steepness, or slope, of a line in a distance-time graph to determine the speed of an object if speed is constant. The slope of the line is calculated by dividing the change in distance by the change in time for that time interval.
Calculating DNA concentration in PCR product?
In order to calculate the concentration of DNA in PCR products (usually expressed in micrograms permicroliter), one had to first establish a standard curve that correlates the concentration of DNA and its absorbency at 280 nm. This standard graph can be set up by preparing serial dilutions of DNA of known concentration and then measuring the absorbency of the sample at 280nm. Ideally, a linear graph is seen. Now that a standard graph has been established, the product obtained at the end of a PCR reaction can be sampled for absorbency measurement. Using the absorbency value, one can estimate the concentration of DNA be interpolating on the standard graph. There are however, several calculations that that to be made in order to arrive at the final answer.
Why is the order of the numbers in an ordered pair is important?
Ordered pairs are used to locate points on the graph. The first number in an ordered pair corresponds to the horizontal axis, and the second corresponds to the vertical axis.
What is indeference curve?
Indifference curve is a curve. A curve that is being intersected with the budget line. In order to show the maximum satisfaction. Dave Ono:
Y-values decrease as the x-values increase how is it shown on a table and a graph?
If the table consists of a column of x values and a column of y values, and if the x values are in increasing order, ten the y values will be in decreasing order. The graph of y against x will have a downward slope. That is, the line or curve will be going from top left of the chart to bottom right.
What is the exponential equation that models the spread of Swine Flu?
Here is the equation, as of May 7th. I graphed the number of swine flu cases versus date on excel (with April 23 being Day 1). The graph was an exponential curve. In order to make a good regression, the curve has to be linear. So, I took the natural log (ln) of the cases, in order to make a near-linear graph. Then, I calculated the trendline. # swine flu cases = e^[1.6895 + 0.3442(date)] **Note, date = the number of the day, if you start with 4/23 as day one, 4/24 as day two, and so on. I picked 4/23 because that's when most other graphs I've seen of swine flu cases starts. **Also note: this curve could change with time. Eventually, it will look more like a bell-curve than an exponential curve.
What is mean by first order continuity curve?
The first order continuity curve is a term used in geometry to describe parametric first derivatives that are in proportion at the intersection on at least two successive sections of the curve.
How does changing the signs of the coefficients affect the graph of a polynomial?
For a polynomial of order n there are n+1 coefficients that can be changed. There are therefore 2^(n+1) related polynomials with coefficients of the same absolute values. All these generate graphs whose shapes differ.If only the constant coefficient is switched, the graph does not change shape but moves vertically. If every coefficient is switched then the graph is reflected in the horizontal axis. For all other sign changes, there are intermediate changes in the shape of the graph.
