what lines would you use to solve
-3x-2=2x+8?

The left side is represented by the purple line and the right side is represented by the orange line.
Here we want to solve:
-3x-2=2x+8
Then the two linear equations that we need to use are:
y = -3x - 2
y = 2x + 8
The first equation, for the left side, has a negative slope and intercepts the y-axis at y = -2, that line is the purple line.
The right side has a positive slope and intercepts the y-axis at y = 8, that line is the orange line.
So the two lines that must be used are the purple and orange ones.
