Question

A line passes through the points (3,-12) and

Answer 1

Answer:

k = - 18

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 2

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

with (x₁, y₁ ) = (3, - 12) and (x₂, y₂ ) = (6, k)

m = $\frac{k+12}{6-3}$ = $\frac{k+12}{3}$ = - 2 ( multiply both sides by 3 )

k + 12 = - 6 ( subtract 12 from both sides )

k = - 18
