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 services. Is there a direct variation?

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
