C. -2 + 4(x + 3)

-2 + 4x + 12 = 4x + 10

D. 3x + 5(x - 1)

3x + 5x - 5

8x - 5

17.) A, B, D

A. 1/5(x - 50)

What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?​
Hitman42 [59]

Answer:

\large\boxed{y-12=\dfrac{5}{6}(x+9)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slope</em>

<em>(x₁, y₁)</em><em> - point on a line</em>

<em />

We have

m=\dfrac{5}{6},\ (-9,\ 12)\to x_1=-9,\ y_1=12

Substitute:

y-12=\dfrac{5}{6}(x-(-9))\\\\y-12=\dfrac{5}{6}(x+9)
