Answer:
c
Step-by-step explanation:
when 2 lines are perpendicular, the product of their gradients will give you -1 thus the gradient of the equation is
2 x m = -1
m = -1/2
and since it will pass thru point (-3, 7)
thus it will results in (x+3) and (y-7)
Answer:
Part A. 991.25

Part B. 253+71.25=324.25
17.25*14 2/3=324.25
Part C. 666.75
666.75 because 991.25-324.25=666.75
