does the data in the table represent a linear function? if so, wirte a rule for the function.

(below is what the table looks like)
x | -2| -1| 0 | 1| 2|
y | -7| 1| 8 | 17| 25|

yes; y = 8x +9

1. what is (25-17)/(2-1) ?
8

what is
(1 - -7) /( -1 - -2) ?
8/1 = 8

humm looks like slope = 8 so far

(17 -8)/ (1 - 0) = 9 !!!!!
oh my, not the same slope
crash
not on a straight line of constant slope

7. It is almost a linear function, if the 8 becomes a 9, i.e. the y-values become
-7,1,9,17,25.
