We know the slope is -1, because perpendicular line's slopes are always the negative reciprocal. We plug (5, -3) in to get:
-3 = -5 + b
b = 2
So we get C. y = -x + 2.

Answer:
there needs to be at least 77 cakes sold
Step-by-step explanation:
let 'c' = # cakes sold
3.25c ≥ 250
c ≥ 250÷3.25
c ≥ 76.9
He is correct and incorrect. 2 and 4 can create factors but they can also be factors of other numbers. So 8 can be a factor of bigger whole numbers and can also have it own smaller factors.
A^2 + b^2= c^2
(a,b,c are right triangle sides)
