See the picture down below
Step-by-step explanation:
When you are drawing a line you should first mark the y-intercept, which in this case it's (0,-3) because the the b in the equation is -3. Then we will go 2 units up then 1 unit right. Keep going until you've run out of room. Then draw the line going through all the points.
Answer:
$65/hour
Step-by-step explanation:
Let C(h) represent the total amount payable to the plumber. Then:
C(h) = $75 + (rate)(2 hr) = $205. Solve for the "fixed hourly rate."
Subtracting $75 from both sides, we get:
(rate)(2 hr) = $130.
Dividing both sides by (2 hr) results in (rate) = $65/hour
