Answer:
x'= (-11,-8)
Step-by-step explanation:
First, make a graph and plot point "x" (the rest of the points are unnecessary)
Next, count how many units (from point "x") it takes you to get to the x-axis (which is the horizontal line) The answer to that is 8
Then, from the point you ended on, count 8 down. You should get (-11,-8)
