Answer: y = 2x - 5

Step-by-step explanation:

Use the slope formula: slope (m) = [tex]\frac{y_{2}-y_{1}}{x_[2]-x_{1}}[/tex]

[tex]m = \frac{-9-7}{-2-6}[/tex]

  = [tex]\frac{-16}{-8}[/tex]

  = 2

Next, input ONE of the points and the slope into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 7 = 2(x - 6)

y - 7 = 2x - 12

     y = 2x - 5
