A computer technician charges a flat rate for home vist plus $55 per hour. The technician bills $190 for a 2-hour home vist to install a new hard drive. The equation y-190=55(x-2) gives the total amount y the technician charges for x hour of work. What is the equation in slope-intercept form?

y - 190 = 55(x - 2)....distribute thru the parenthesis
y - 190 = 55x - 110....now add 190 to both sides
y = 55x - 110 + 190..simplify
y = 55x + 80 <== slope intercept form (y = mx + b)
