What is the slope?
The steepness of a line, and a ratio between the change in y and the change in x between any two points on a line.
What is the formula for the slope?
Change in Y over Change in X
What is this symbol?
The change in y or x.
How do you find the change in x?
Subtract the x coordinate of the first point from the x coordinate of the second point.
How do you find the change in y?
Subtract the y coordinate of the first point from the y coordinate of the second point.
What is the point-slope form?
