Answer:

Step-by-step explanation:
Given
Horizontal Line

Required
Determine the equation
The equation is calculated using:

Where

Because the line is a horizontal line, then:

Substitute 0 for m and values for x1 and y1 in 



Subtract 2 from both sides


Hence, the equation is: 
Miles in 2 hours = 22
Rate of distance = 22/2
= 11 miles/hour
So miles in h hours = 11h
Miles in 4 hours = 11 * 4
= 44 miles
Answer is
11h , 44 miles
Answer:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374
so, option-D...........Answer
