Final answer:

To find the missing y-coordinate for the point (2, y) with the function y = -5x - 8, substitute x=2 into the equation to get y = -5(2) - 8, which simplifies to y = -18. Hence, the coordinate pair is (2, -18).

Step-by-step explanation:

Step-by-step Explanation

To determine the missing coordinate value of (2, y) for the function y = -5x - 8, you need to substitute the x-coordinate (which is 2) into the equation and solve for y:

First, plug in x = 2 into the equation: y = -5(2) - 8.

Multiply -5 by 2 to get -10.

Add -10 to -8 to get -18.

Therefore, the value of y when x = 2 is -18.

The complete coordinate pair is (2, -18).
