Marcy spent 8 minutes on the phone while routing 4 phone calls. In all, how many phone calls does Marcy have to route to spend a total of 20 minutes on the phone? Assume the relationship is directly proportional.

Marcy will need to route 10 calls to spend a total of 20 mintes on the phone.

Step-by-step explanation: 1 call = 2 minutes.

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

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
