Answer:
Step-by-step explanation:
The function
gives the mass of the car as a function of the number of passengers in it.
And the function
gives the potential energy of the car as a function of the car's mass.
Now if the height of the ramp is 30 meters, we have
And to find the potential energy as a function of the number of passengers, we just substitute into
to get:
which gives the potential energy as a function of the number of passengers.

Given:
Find:
Solution: In order to get the equation, we need to first use the point-slope form to help us sort out our information and then we solve for y.
<u>Plug in the values</u>
<u>Simplify and solve for y</u>
Therefore, the final answer would be that the equation that has a slope of -1/4 and passes through (4, -5) is y = -1/4x - 4.
