An electrician is hired to install outdoor lighting. The electrician claims that the relationship between the number of hours worked and the total work fee is porportional. The fee for 5 hours of work is $255

If we have two variables and can write a relationship between them as:

Then we say that varies directly as or is directly proportional to

In this case, let's say:

Then since we know that the fee for 5 hours of work is $255, then the constant of proportionality is:

Therefore, our model can be written as:

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
