A table of data is linear if the x and the y are increasing by the same ratio throughout the set. For instance, the following table is linear: x y 3 6 4 8 5 10

this table is very basic, but it is also linear. It is linear because x and y stay at the same ratio. the ratio, or slope is 2, because y is always double x. Figure out whether the following tables are linear: x y --- x y ---x y 9 3 ---5 18 -11 4 15 5 -12 39 31 6 21 7 -17 54 ---76 9 39 13 20 63 ---95 10 -Nico

y=1/3x y=3x+3 not linear
