The Quick Car Retail Shop charges a $20 fee plus $45 an hour for labor. Any automobile parts needed are not included in this charge. What is the cost of the repair job, y, if Leon’s car did not need any parts, but the repair took x hours?

Respuesta :

Answer:

y=45x+20

Step-by-step explanation:

y=45x+20

45 is constant, so every hour it takes, 45 dollars will be added (slope)

20 is the starting point (y- intercept)

Using formula y=mx+b

y=45x+20
