Question

Find the slope of the line containing the points (4,9) and (6,-5).A: -5/11B: -7C: -11/5D: -1/7

Answer 1

x₁ = 4

y₁ = 9

x₂ = 6

y₂=-5

We will use the slope formula below;

$\text{slope =}\frac{y_2-y_1}{x_2-x_1}$

substitute the values into the formula

$\text{slope =}\frac{-5-9}{6-4}$

$=\frac{-14}{2}$

$=-7$
