(7,2) , (3,0) 7-3=4 as denominator, and 2-0=2 as the numerator equaling 2/4 which is 1/2

Answer:

The missing y -coordinate is 0.

Explanation:

Here we know the slope but must find the y-coefficient of one of the points.

y - 2

The slope is m = 1/2 = rise / run = ----------

3 - 7

y - 2

or 1/2 = ---------- which simplifies to -2 = y - 2, which yields y = 0.

-4

The missing y -coordinate is 0.
