Answer:
b=2A/h-a
Step-by-step explanation:
A=1/2h(a+b)
Multiplying by 2
2A=h(a+b)
Dividing by h
2A/h=a+b
Subtracting a
2A/h-a =b
b=2A/h-a
Answer:

Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
