Question

(8,y) and (-2,4);slope =-1/5

Answer 1

Answer:

y = 2

Step-by-step explanation:

Calculate the slope m and equate to - $\frac{1}{5}$

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

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (8, y)

m = $\frac{y-4}{8+2}$ , that is

m = $\frac{y-4}{10}$ = - $\frac{1}{5}$

Multiply both sides by 10 to clear the fractions

y - 4 = - 2 ( add 4 to both sides )

y = 2
