Part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points) (10 points)

We observe that we have the following system of equations:
y = 4x
y = 2x-2
The solution to the system of equations is an ordered pair (x, y), that is, a point in common that both functions have.
Part B:
x y = 4x y = 2x-2
-3 -12 -8
-2 -8 -6
-1 -4 -4
0 0 -2
1 4 0
2 8 2
3 12 4
The solution is the ordered pair:
(x, y) = (-1, -4)
Part C:
