3x-34 = 2x -5
3x-2x = 34 -5
x = 29
plug the 29 back into the second equation ( or the first , your choice )
y = 2 (29) -5 = 58-5= 53
(29, 53)

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)
