13.1.39 Complete the ordered pair for the equation $y=-7 x+8$. $(\ldots, 36)$ Complete the ordered pair. $, 36)$ (Type an integer or a simplified fraction.)

Step 1 ：The question is asking for the x-value in the ordered pair (x, y) that makes the equation true when y is 36. To find this, we can substitute y = 36 into the equation and solve for x.

Step 2 ：Substitute y = 36 into the equation $y=-7 x+8$ to get $36=-7 x+8$.

Step 3 ：Solve the equation $36=-7 x+8$ for x to get x = -4.

Step 4 ：The solution to the equation is x = -4. This means that the ordered pair that completes the equation when y = 36 is (-4, 36).

Step 5 ：Final Answer: The ordered pair is \(\boxed{(-4, 36)}\).
