Step-by-step explanation:
Let h be the number of hours.
Total Cost = Fixed Costs + Variable Cost
= Initial Fee + Hourly Charge
= 75 + 9h
Given,
Since the car cannot be rent part of an hour, the highest possible whole number is 19 hours.
Answer: Slope = 2/5
Concept:
Here, we need to know how to find the slope.
Slope = (y₂ - y₁) / (x₂ - x₁)
If you are still confused, please refer to the attachment below for a clearer version of the formula
Solve:
<u>Given information</u>
(x₁, y₁) = (-6, 2)
(x₂, y₂) = (4, 6)
<u>Given formula</u>
Slope = (y₂ - y₁) / (x₂ - x₁)
<u>Substitute values into the formula</u>
Slope = (6 - 2) / (4 - (-6))
<u>Simplify values in the parentheses</u>
<u>REMEMBER to change [+, -] signs when there is a [-] sign in front</u>
Slope = 4 / (4 + 6)
Slope = 4 / 10
<u>Divide both numerator and denominator by 2 to get the simplest form</u>
Slope = (4 ÷ 2) / (10 ÷ 2)
Slope = 2/5
Hope this helps!! :)

This is easy! Just use the point-slope form: 
Plug in the values:
-1 - 4 = m(2 - (-3))
Combine like terms
-5 = 5m
Divide both sides by 6
m = 5/-5 or
m = -1
Plug in the values:
-1 - 4 = m(2 - (-3))
Combine like terms
-5 = 5m
Divide both sides by 6
m = 5/-5 or
m = -1
