Let's replace x with -4 and simplify
y = (x/4) + 7
y = (-4/4) + 7
y = -1 + 7
y = 6
This means x = -4 and y = 6 pair up together.
So 6 goes in the box under the -4
----------------------------------------------------------
Repeat those steps for x = 0
y = (x/4) + 7
y = (0/4) + 7
y = 0 + 7
y = 7
So 7 goes in the box under the 0
----------------------------------------------------------
Let's repeat those steps for x = 4
y = (x/4) + 7
y = (4/4) + 7
y = 1 + 7
y = 8
So 8 goes in the box under the 4
----------------------------------------------------------
Lastly, for x = 8, we get
y = (x/4) + 7
y = (8/4) + 7
y = 2 + 7
y = 9
9 goes in the box under the 8
----------------------------------------------------------
The y outputs we got were: 6, 7, 8, 9
Notice how each time y increases by 1, x goes up by 4.
This means slope = rise/run = 1/4
We can think of x/4 as (1/4)x to help see that the slope is 1/4.

Step-by-step explanation:
Given
Solving (a): What does h represents
From the instruction in the question, we understand Cycle city charges an additional 0.75 per hour.
This implies that h represents the additional hour of rentals
Solving (b): What does 15 represents
From the instruction in the question, we understand Cycle city charges an a base charge of $15
This implies that 15 represents the base charge
Solving (c): 0.75h
Referring back to (a) where h represents the additional hour of rentals
0.75h represents the total charges for the additional hour
