Question

What is the slope of (-8, 8) and (-2, 5)

Answer 1

Slope is -1/2

Explanation:

The given points are (-8, 8) and (-2, 5)

We apply the slope formula:

$\begin{gathered} m\text{ = }\frac{y_2-y_1}{x_2-x_1} \\ x_1=-8,y_1=8,x_2=-2,y_2\text{ = }5 \end{gathered}$$\begin{gathered} m=\frac{5-8}{-2-(-8)} \\ \\ \end{gathered}$

Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.

$\begin{gathered} m\text{ = }\frac{-3}{-2+8}=\frac{-3}{6} \\ \text{slope = m = -1/}2 \end{gathered}$

Hence, the slope is -1/2
