Solution
The correct option is By2−y1x2−x1 Slope of a line is defined as the ratio of the rise to the run.
In the figure given, the two points are (x1,y1) and (x2,y2).
As we can see, the rise, which is the change in the y coordinate is y2−y1
and, the run, which is the change in the x coordinate is x2−x1
