Question

What is the slope of the line that contains the points (7, -3) and (-7, 4)?

Answer 1

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$m = \dfrac{-3 - 4}{7 - (-7)}$

$m = \dfrac{-7}{14}$

$m = -\dfrac{1}{2}$

Answer: The slope is -1/2.

Answer 2

Slope = (y2-y1)/(x2-x1) = (4-(-3))/(-7-7) = 7/(-14)= -1/2  or -0.5
