Answer 1

Answer 2

do you see any pattern here? what could we do to 32 to get 20?

Answer 3

1.6 x 20 would be 32

Answer 4

but if we do 2 x 1.6, do we get 14?

Answer 5

the function rule is much simpler than you think

Answer 6

what else can we do to 32 to get 20?

Answer 7

Subtract it by 12

Answer 8

yes! 32 - 12 = 20. so the function rule would be y = x - 12.

is it true for 14 and 2? does 14 - 12 = 2?

and -2 and -14? does -2 - 12 = -14?

Answer 9

it is true for all the ordered pairs already in the table. so y = x - 12 is our rule. you can now use the rule to fill in the table
