Step-by-step explanation:
The slope formula of the line passing through the points (x_1,y_1) and (x_2,y_2) can be found by:
m={y_2-y_1}/{x_2-x_1}
So to find the slope of a line segment joining the points ( 2, - 5) and (- 2, 4).
First, label the points as x_1 = 2, y_1 = - 5, x_2 = -2 and y_2 = 4
m={y_2-y_1}/{x_2-x_1} =
= {9}/{-4}
= {-9}/{4}
So, the slope (m
) = -9/4.
