When would it be best to use the slope point form to find the slope of a line?
The slope-point form, expressed as (y - y_1 = m(x - x_1)), is best used when you have a specific point on the line, ((x_1, y_1)), and the slope (m) of the line. This form is particularly useful for writing the equation of a line quickly when you know these two pieces of information. It's also effective for graphing, as it allows you to easily plot the point and use the slope to find additional points on the line.
What is the difference between the point slope formula and the slope intercept form of a straight line?
The point-slope formula of a straight line is expressed as (y - y_1 = m(x - x_1)), where (m) is the slope and ((x_1, y_1)) is a specific point on the line. In contrast, the slope-intercept form is given by (y = mx + b), where (b) represents the y-intercept, the point where the line crosses the y-axis. Essentially, the point-slope form is used to write the equation of a line given a point and its slope, while the slope-intercept form is used to express the line in terms of its slope and y-intercept.
What makes the term used to describe the relationship between variables whose graph is a straight line?
There are many terms used for the purpose: slope, gradient, relationship, regression, correlation, error, scatter; as well as phrases: line of best fit, least squares, maximum likelihood. The question needs to be more specific.
Why can't a vertical line be used to represent rate of change?
the rate of change is related to the slope; the higher the slope, the higher the rate. If the line is vertical, that is infinite slope or infinite rate of change which is not possible
Graphing linear equation using the slope and y-intercept of the line?
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
What is the formula used to find slope?
The slope of a straight line equation is: y2-y1/x2-x1
Which expression is used to find the slope of a line?
The steepness of a line can be measured as the slope of a line. The letter 'm' is used to denote the slope and it can be expressed as m= (y coordinate of A- y coordinate of B)/ (x coordinate of A- x coordinate of B). A and B are two points on the line.

Why is it important to find the slope of a line?
A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.A line is used to describe the relationship between two variables, often an independent variable that is measured on the x-axis, and a dependent variable that is measured along the y-axis.The slope of the line tells you how much y will change for every unit change (change of -1 or +1) in x.

Why is a best fit line used to find slope instead of using the data points?
Because the data points are generally not all in line with each other. If you connect the dots,from one data point to the next and then to the next, you usually get a zig-zag line of manysegments, where the slopes of the segments are all different and cover a wide range. It wouldbe impossible to decide what the "real" slope of the data is. The "best fit" line is a line that findsthe pattern buried in the zig-zag data, giving each data point its best share of determining the bestsingle equation to represent the whole batch of points. That's why it's called "best".
What is the point-slope formula and how is it used?
Given a straight line with slope m and a point (p,q) on the line, the point-slope formula of the line is (y - q) = m(x - p) It is used to represent a straight line in the Cartesian plane. This allows techniques of algebra to be used in solving problems in geometry.
What is a slope used for?
It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]

What best explains how a plot of concentration vs time for a reactant of a chemical reaction can be used to determine the instantaneous rate of a reaction at time equals 10 s?
1) Find time = 10 s on the curve. 2) Draw a line tangent to the point time = 10 s on the curve. 3) Use two points on the tangent line to find the slope of the line. 4) The slope of the line is the instantaneous rate in M/s.
