Answer: the average rate of change is 4.
Step-by-step explanation:
The average rate of change is the slope. Therefore, you must use the following formula for calculate the slope:

As you can see in the table, when x=5, y=-2 and when x=9, y=14. Then the points you must substitute into the formula are:
(5,-2) and (9,14)
Then, you obtain:

1.Austion bc he is taking more time
2. 1/2 of the stair case
3.the whole stair case
4.Dylan
5. Dylan he takes the same jumps just skips steps and jumps further and higher
First, you want to identify the slopes and y-int.
Equation 1 = y = -2x + 2
Slope = -2
y-int. = 2 or (0,2)
Equationt 2 = y = 2x + 3
Slope = 2
Y-int. = 3 or (0,3)
To graph, first plot the y-intercepts. Then do the slopes.
Slope = -2
Down 2 over 1 (to the right)
Slope = 2
Up 2 over 1 (to the right)
Then just connect the dots in a line!
