Question

A computer repair service charges $50 fordiagnosis and $35 per hour for repairs. Let x bethe number of hours it takes to repair acomputer. Let y be the total cost for repairs.

Answer 1

From the question, we have here a situation that we can state using a linear function as follows:

$y=50+35x$

Then, in this case, we have that the total cost for repairs is given by the linear equation above.

The equation in slope-intercept form is given by the equation above since the general form of that equation is:

$y=mx+b$

Then, the equation in slope-intercept form is:

$y=35x+50$

We can graph the line using the x- and the y-intercept of the line. The x-intercept is the point on the x-axis where the line passes through, and at this point, y = 0. Likewise, the y-intercept is the point where the line passes through the y-axis, and at this point x = 0. Then, we have:

The x-intercept
