Question

Find the slope of (-3, -8)(-12, -20)

Answer 1

Answer: $\frac{4}{3}$

Step-by-step explanation:

Let (-3, -8) = (x₂, y₂)  and (-12, -20) = (x₁, y₁)

Slope (m) = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

                = $\frac{-8-(-20)}{-3-(-12)}$

                = $\frac{-8+20}{-3+12}$

                = $\frac{12}{9}$

                = $\frac{4}{3}$    simplified
