Answer:
see below
Step-by-step explanation:
The y-coordinate measures the vertical distance relative to the x-axis on the coordinate plane. A point that is 3 units below the x-axis will have a y-coordinate of -3. The y-coordinate is listed 2nd in an (x, y) ordered pair, so you're looking for an ordered pair with -3 in the second spot.
2/3x=10
3/2 x 2/3x = 3/2 x 10
x=30/2=15
