Question

May I have help on question 14

Answer 1

y=mx+b

(6,6) (3,8)

6m+b=6

3m+b=8

6m+b-3m-b=-2

3m=-2

m = -2/3

-2+b=8

b=10

y = -2/3x+10

I choose 12.

-2/3(12)+10

=2

so put x as 12; y as 2.

Answer 2

We want to add an x value we have not used before. A function has EVERY X IN A DOMAIN going to ONLY ONE Y value.

6,3,9,7 are already used for x.

so you can put in x = 8 and y = 12 as an answer. That will work and show a function. There are also other answers.
