Question

I need help pls, what’s the answer?

Answer 1

Answer:

x₂ = - 3

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to $\frac{5}{6}$

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

with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)

m = $\frac{-1-9}{x_{2}-9 }$ , that is

$\frac{-10}{x_{2}-9 }$ = $\frac{5}{6}$ ( cross- multiply )

5(x₂ - 9) = - 60 ( divide both sides by 5 )

x₂ - 9 = - 12 ( add 9 to both sides )

x₂ = - 3
