Fast i need 100% contractor 3 gives mrs. solar the following fee table showing her charges for the contract work. a) what is the rate of change? what does this mean in a real-world context? (b) write an equation in point-slope form to represent the total cost, y, given x hours. (c) graph the equation written in part (b). (d) what is the y-intercept? what does this mean in a real-world context?

rate of change is the slope

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

m= (180-120)/(3-2)

m = 60/1

m = 60

b.  point slope form

y-y1 = m(x-x1)

y-120 = 60 (x-2)

c see attached graph.  x>=0 since it is hours

d the y intercept is

y -120 = 60x-120

add 120 to each side

y = 60x
