Need an answer TODAY! Please only give correct and clean answers to this question, I will give Brainliest Answer if you do.

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the solutions of the equation 8x = 2x + 2.

Part B: Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between −3 and 3.

Part C: How can you solve the equation 8x = 2x + 2 graphically?

A. When you equalize two equations, geometrically you are trying to find the intersection point of them, i.e. find the common point of them. So the x coordinate of the intersection point is basically the solution.

B. You can simply plug in numbers from -3 to 3 and list the values by yourself.

C. Graphically, draw each equation, and find the x coordinate of the intersection point.

FYI, the solution is x = 1/3
