Answer 2

ANSWER

See graph

EXPLANATION

We need to find the y-values for the ordered pairs by substituting the x-value in to the relation

when

`x = - 2`

`y = 3( - 2) + 3`


`y = - 6 + 3`


`y = - 3`

This gives the ordered pair

`(-2,-3)`

when

`x = 1`

.

`y = 3(1) + 3`


`y = 3 + 3`


`y = 6`
This also gives the ordered pair


`(1,6)`

when

`x = 2`

`y = 3(2) + 3`

.

`y = 9`

This also gives the ordered pair,

`(2,9)`

We now plot all the ordered pairs and draw a line through them.
