Question

CARD 2 Linear Non-Unear 7 * * > CARD SORT TALES

Answer 1

For each table, we need to find if the table represents a linear or nonlinear function

If it is linear we can calculate a slope, otherwise, it is non-linear.

For the first table

x y

-2 4

0 6

2 9

for the first and second point

`m1=(6-4)/(0+2)=(2)/(2)=1`

for the second and third point

`m2=(9-6)/(2-0)=(3)/(2)`

Because both the slopes are different, this table is non-linear

We need to do the same for each table. If they have different slopes the table is non-linear if they have equals slopes they are linear.
