Answer:

(5, 3)

Step-by-step explanation:

x = 17 - 4y \\ y = x - 2

Substitute x into y:

y = (17 - 4y) - 2 \\ y = 15 - 4y \\ y + 4y = 15 \\ 5y = 15 \\ y = 3

Substitute y into x:

y = x - 2 \\ 3 = x - 2 \\ 3 + 2 = x \\ x = 5

Therefore your answer is (5, 3).

What is (5,1) reflected on the y axis
asambeis [7]

Answer:

(-5 , 1)

Step-by-step explanation:

If you are reflecting over the x-axis, you are changing the sign of the y.

If you are reflecting over the y-axis, you are changing the sign of the x.

In this case, you have the point (5 , 1). You are reflecting over the y-axis, which means that you are flipping the sign of the x value.

(5 , 1) reflected over the y-axis is (-5 , 1)

(-5 , 1)
