Answer: It represent Parallel lines which means it have no solution which also means they never intersect.
Explanation:
y=3x will be going through the origin and y=3x-3 will be going through the y intercept -3.
Since the lines has the same slopes and different y intercept we will have no solutions.
Solve the equations to prove it.
First set them equal each other and solve for x.
3x - 3 = 3x
-3x -3x
-3 ≠ 0
As you can see -3 does not equal 0 so there will be no solution.
