x= 2, 4, 6
y=0, 4, 8

Please next time, write this in mathematical form. I can't decipher your question.
OpenStudy (anonymous):
oops. sorry :///
OpenStudy (anonymous):
its a table and the x is 2, 4, and 6
and the y is 0, 4, 8
OpenStudy (anonymous):
and it's asking what the rate of change is if it's -2, -1/2, -1/2, and 2

x = 6 and y = 8
jimthompson5910 (jim_thompson5910):
good, we don't need to worry about the x = 6 and y = 8 pair
jimthompson5910 (jim_thompson5910):
the difference from x = 2 to x = 4 is 2 units (4 - 2 = 2)
the difference from y = 0 to y = 4 is 4 units (4 - 0 = 4)
divide the two differences to get
(y difference)/(x difference) = 4/2 = 2
jimthompson5910 (jim_thompson5910):
another way to think of it: the average rate of change is the slope of the line through the two points (2,0) and (4,4)

so my answers 2!
