Answer:
Garage A: y = 2x +5
Garage B: y = x +7
Step-by-step explanation:
The slope is the amount the charge goes up when hours increase by 1. For Garage A, that is 2 dollars per hour. For Garage B, it is 1 dollar per hour.
The y-intercept is the charge for 0 hours. For Garage A, that is $5. For Garage B, it is $7.
The equation is ...
y = slope · x + (y-intercept)
Garage A: y = 2x +5
Garage B: y = x +7
_____
The values we used for slope and intercept for Garage B were read from the graph.
