Astore's change in total revenue over a 4-month period is −$1,240 . what is the average change in revenue per month for that period? −$4,960 −$310 $310 $4,960

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
