Question

a technician charges $25 per hour plus $50 for a house call to repair home computers. Make a table and a graph to show the cost for 1 2 3 and 4 hours of home computer repair service is there a direct variation?

Answer 1

Explanation:

First, let's formulate an equation. Let the independent variable be x to denote the number of hours. The dependent variable is y to denote the total cost. The equation should be:

y = 25x + 50

The table and graph is shown in the picture. Just use values of x as 1, 2, 3 and 4, find y and plot the points.
