To find the equation of the line we will need to find slope and the y-intercept.
Given: (-3,9), (-3,-5)
What we know:
slope=m=(y2-y1)/(x2-x1)
m=(-5-9)/9-3-(-3))=-14/0
m=undefined
When slope=m is undefined we have an a line x=-3. That means that for every y the x value is always -3. This line x=-3 is a vertical line on the graph at -3.

Answer: A.30
Step-by-step explanation:
Let's solve your equation step-by-step.
8x−3(2x−4)=3(x−6)
Step 1: Simplify both sides of the equation.
8x−3(2x−4)=3(x−6)
8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)
8x+−6x+12=3x+−18
(8x+−6x)+(12)=3x−18(Combine Like Terms)
2x+12=3x−18
2x+12=3x−18
Step 2: Subtract 3x from both sides.
2x+12−3x=3x−18−3x
−x+12=−18
Step 3: Subtract 12 from both sides.
−x+12−12=−18−12
−x=−30
Step 4: Divide both sides by -1.
−x/-1 = -30/-1
<h3>x=30</h3>
