Which statements about this function ARE true?

Option A

Step-by-step explanation:

I, II, and III are all correct because they truly represent the function c(t)=150t+100, where the initial call fee is $100, the plumber charges $150 per hour because the coefficient 150 is the constant, and the number of hours is represented by t because it’s being multiplied by the coefficient 150. They are all true. So option A is the correct one.

Hope this helps and answers your question.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
