1. Problem Description

The problem asks us to solve the system of equations
y=2x+2y = -2x + 2
4y+8x=84y + 8x = 8
by graphing.

2. Solution Steps

First, let's simplify the second equation:
4y+8x=84y + 8x = 8
Divide by 4:
y+2x=2y + 2x = 2
Subtract 2x2x from both sides:
y=2x+2y = -2x + 2
Now we have the two equations:
y=2x+2y = -2x + 2
y=2x+2y = -2x + 2
Since both equations are identical, they represent the same line. This means that there are infinitely many solutions, and any point on the line y=2x+2y = -2x + 2 is a solution to the system of equations.
To graph the line, we can find two points on the line.
If x=0x=0, then y=2(0)+2=2y = -2(0) + 2 = 2. So the point (0,2)(0, 2) is on the line.
If x=1x=1, then y=2(1)+2=0y = -2(1) + 2 = 0. So the point (1,0)(1, 0) is on the line.
Since the two equations are the same line, the solution is all points on the line y=2x+2y = -2x + 2.

3. Final Answer

Infinitely many solutions. The two equations represent the same line.
