Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
Parallel lines have the same slope.
We have the equation in the slope-intercept form (y = mx + b)

Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):

Answer:
a. $45 an hour
b. 5.25 hours
Step-by-step explanation:
a. The plumber charges $75 per job, so it is irrelevant to the number of hours they work. 45(h) is $45 multiplied by the number of hours they work.
b.
First, plug the numbers into the equation, the cost being C(h):
311.25 = 45(h) + 75
Next, subtract $75 as it is a set price that is always payed:
236.25 = 45(h)
Then, divide both sides by 45 to find how many hours were worked:
h = 5.25
Hours = $5.25
