A computer technician charges a flat rate for home visits plus $ 55 per hour. The technician bills $190 for a 2-hour home visit to install a new hard drive. The equation y โ 190 = 55(x โ 2) gives the total amount y the technician charges for x hours of work.
What is the equation in slope-intercept form?
y = 55x + 190
y = 55x + 80
y = 190x + 55
y = 2x + 55
What does the y-intercept in this equation represent?
the rate of change
the total cost
the flat rate
If the technician charged $327.50, then the technician worked
hours.
