Question

Find the slope of the line that passed though the two points (0,5) and (-9, -4)

Answer 1

To find the slope, use the slope(m) formula:

$m=\frac{y_2-y_1}{x_2-x_1}$        and plug in the two points

(0, 5) = (x₁, y₁)

(-9, -4) = (x₂, y₂)

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

$m=\frac{-4-5}{-9-0}$

$m=\frac{-9}{-9}$    [two negatives cancel each other out and become positive]

m = 1      The slope is 1
