Answer:
363-138=-5x
Step-by-step explanation:
Let c = cost
We know that the total cost is $363:
363-??????
We also know that he spent $138 on parts:
363-138?????
And we are solving for the cost of labor per hour:
363-138=5x
We can use this equation to find the total cost of labor per hour.
Hence, your equation will be 363-138=5x
y = 3/4x -2
slope = rise/run = 3/4
y intercept is where the line crosses the y axis, it crosses at -2
1/6
Answer: it would be 7.5
