A handy man charges $25 per hour, plus a $40 service fee. Write an equation to represent this situation, and then determine the cost of a 3 hour service call

Step-by-step explanation:

Straightline equation problem

given data

charges per hour= $25

service fee= $40

time =3 hours

the equation can be represented using the equation of line

y=mx+c

y= the total charges

x= the number of hours

c= the service fee

m= the charge per hour

y=25x+401

for x=3

y=25(3)+40

y=75+40

y=115

the total is $115

answer

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
