Amy and her family were traveling during their vacation. At point 1, her watch said 11:15. It took her 80 miles to get to Point 2 at 1:15. Based on this information, what is the unit rate (in miles per hour) of the car?

40 miles per hour

Step-by-step explanation:

From 11:15 to 1:15 it's 2 hours.

They drove 80 miles in 2 hours.

unit rate = speed = distance/time = (80 miles) / (2 hours) = 40 miles per hour

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
