The answer would be 400,000; 70,000; 50; 2.
Hope this helps!
1) find the corresponding y values for when x = 0 and when x = 4,
when x = 0, y = 4
when x = 4, y = 4
the coordinates are (0,4) and (4,4)
2) to calculate the average rate of change, find the slope of the two points:
(0,4) (4,4)
(change in y) 4 - 4 = 0
(change in x) 4 - 0 = 4
0/4 = 0
the average rate of change is 0!
the denominator would be 12
You can you 72 which would make 2/8 18/72 and 3/9 24/72 which makes the sum 42/72.
