Cynthia drove 150 miles at a rate of 50 miles per hour. write an equation that could be used to find out how long it took her to drive the 150 miles. 112. how long did it take cynthia to drive the 150 miles? see #111.

150/50=3

Step-by-step explanation:

she drove 150

Each hour she drove she went 50 miles

we know that if we miltiply 50 x 3 it will equal 150 which is the total distance.

you can also reverse multiplication 50x3=150  or 150/50=3

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
