How many roots does the graphed polynomial function have

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit

2x minus y equals 6, x plus y equals negative 3
