A plumber charges $30 for a service call and an additional $25 per hour. Write an equation in slope-intercept form to represent
the cost of service, C, for h hours of service. Then find the cost if the plumber worked 7 hours on a project.

First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10
X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90

Y = 1/5x + b
Plug in point
-8 = 1/5(-10) + b
-8 = -2 + b, b = -6
Equation: y = 1/5x - 6
