Answer:

Step-by-step explanation:
Let
C(t) ---->the total cost of the electrician's services in dollars
t ---> the number of hours
we know that
The linear function in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
the y-intercept is equal to
----> set fee
we have the ordered pair (2,250)
substitute the given values

Solve for m



The linear function is equal to

Let's isolate (1/2)x. To do this, subtract 2 from both sides of the equation, obtaining (1/2)x < -7.
Next, multiply both sides by 2 to eliminate the fraction (1/2):
x < -14
