y = 6x + 9

y = 6x + 2

Therefore y = 6x + 9 = 6x + 2

6x + 9 = 6x + 2

6x - 6x = 2 - 9

0 = -7. This is not true.

So there is:

As we can see, both equations have the same slope but different y-intercepts. This means that both lines are parallel.

If both lines had the same slope and the same y-intercept, they would be essentially the same line, and that would mean infinite solutions.

But, we have the same slope and different y-intercepts. This means that the lines are parallel, and thus have no solution.

Your answer is B. No Solution.
