Isolate y:

A shop rents canoes. They cost $2 per hour to rent. There is an insurance fee you must pay, it's $7...you pay this once, it doesn't matter how long you have canoe. How much will Pythagoras pay if he rents the canoe for 10 hours?

$27

Step-by-step explanation:

7+2x = total cost

x= number of hours with canoe

7+2(10) = 27

$27

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
