Question

Morton needs to have his car repaired. The auto repair shop charges a fixed dollar amount for labor, plus another dollar amount per hour. The coordinate grid shows the graph of the function that represents the situation.
What is the y-intercept of the function and what does it represent?

A.
It is $50, and it represents the hourly rate for the labor charges.

B.
It is $50, and it represents the fixed amount for the labor charges.

C.
It is $75, and it represents the fixed amount for the labor charges.

D.
It is $75, and it represents the hourly rate for the labor charges.

Answer 1

The y-intercept of the function is $50 and it represents the fixed amount for the labor charges.

How to find the y-intercept of a graph?

From the attached graph, we see that the x-axis is represented by time in hours while the y-axis is represented by labor charges in dollars.

Now, from the graph we see that the coordinates are;

(0, 50), (1, 125), (2, 200), (3, 275), (4, 350)

Now, the y-intercept of a linear graph is simply the point at which the graph crosses the y-axis.

In this graph attached, we see that the y-intercept is at the coordinate (0, (0, 50).

Thus, we conclude that  the y-intercept of the function is $50 and it represents the fixed amount for the labour charges.
