Final answer:
The resulting value of y will be the missing coordinate.
Step-by-step explanation:
To find the missing coordinate using the given slope and two ordered pairs, you can use the formula:
Slope (m) = (y2 - y1) / (x2 - x1)
For example, for the first equation (4, y) and (9, 12) with a slope of 8, we have:
8 = (12 - y) / (9 - 4)
Now you can solve for y by multiplying both sides of the equation by (9 - 4), then subtracting 12 from both sides of the equation, and finally dividing both sides by 8.
The resulting value of y will be the missing coordinate.
