Question

A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair. This situation can be described by an equation of the form y=mx+b , where x = the time in hours and y = the cost in dollars. What is the value of b in this equation?

Answer 1

Answer:

b = 40

Step-by-step explanation:

A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.

This situation can be described by an equation of the form y=mx+b , where

x = the time in hours

y = the cost in dollars.

What is the value of b in this equation?

A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair

Writing the above in an equation =

y = $70 × x + $40

y = 70x + 40

Therefore, the value of b in the expression = 40
