Hi there,
The slope can be calculated by subtracting the y-coordinates of the points and dividing by the difference of the x- coordinates. You can choose either point to be (x1, y1) or (x2, y2). Let's have point A be (x1, y1) and Point B as (x2, y2).
Slope = (y2 - y1)
(x2 - x1)
Slope = (2 - (-3)) = 5
(-4 - (-8)) 4
The slope of the line passing thru Points A and B is 5
4
