Question

Which graph can be used to find the solution(s) to 8 – 4x = 2x – 4?

Answer 1

both lines intercept at (2,0) which would be the second graph (B)

Explanation:

Answer 2

To find the solutions to the system of equations we need to graph the following equations:

y = 8 - 4x (Red line)

y = 2x - 4 (Blue line)

The point of interception, is the solution to the system of equations.

By looking at the graph attached, you can see that the point of itersection is at (2,0)
