Answer:
The slope of a line is equal to change in y divided by the change in x. First, put the first point on the coordinate point. Then, represent the X and Y by X1 and Y1. Then, put the second point on the plane, representing the coordinates with X2 and Y2.
Step-by-step explanation:
y2−y1/x2−x1 or just rise / run
