What else can I help you with?
Are trends best observed in scatter plots line graphs or circle graphs?
scatter plot and line graph
Is the scatter plot better then the line graphs?
No, scatter plot gives a rough picture of the data. Line graph gives information on tabulated data
A line that best fits the data points on a scatter plot?
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.
How do you find the slope of a scatter plot after you find the line of best fit?
You find two perfect points (exactly on a point) and use the formula y2-y1 over x2-x1
What is a correlation on a scatter graph in maths?
it is the line in the middle of the crosses
How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.
How do you find the equation of a tangent line?
In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.
How do you find a y-intercept of a scatter plot?
You have to put a line of best fit onto the graph and find where that line crosses the y-axis.
How do you find a line of best fit from scatter plot?
The line of best fit is simply the line that shows the general direction of the graph. The trick is to make the line go through as many points on the graph as possible. Some scatter plots have no line of best fit.
How do you find the equation of a line by the slope?
An equation of a line requires two parameters. The slope, by itself, is not enough.
What is the implication a scatter plot diagram?
It is to find the line of best fit for the co-relation of data
How you find the equation of a line give one point and is parallel to an equation?
i am cute

When looking for a mathematical relationship between two variables use?
line graph or a scatter plot.
What is an example of the equation of a horizontal line?
A horizontal line would be of the form y= (a number). There should be no 'x's involved in the equation.
How can you find the coordinates of two lines mathematically given the equation of both?
Subtract the equation of one line from the equation of the other
How do you find the equation of a line with the x and y intercept?
If the x intercept is a and the y intercept is b, then the equation of the line is bx + ay = ab
