Question

Determine whether each ordered pair is a solution of y = x+3. (2,5) (4,6) (5,8) (3,7)

Answer 1

[see below]

Explanation:

`y=x+3`

(2,5):

`5=2+3\\\\\boxed{5=5}`

The ordered pair is a solution.

(4,6):

`6=4+3\\\\\boxed{6\\eq7}`

The ordered pair is not a solution.

(5,8):

`8=5+3\\\\\boxed{8=8}`

The ordered pair is a solution.

(3,7):

`7=3+3\\\\\boxed{7\\eq 6}`

The ordered pair is not a solution.

Hope this helps.

Answer 2

(2,5) and (5,8)

Explanation:

you can just plug in the numbers to get your answer and if two numbers aren't the same then its not a solution

example: (2,5)

5 = 2 + 3

5 = 5

5 does equal 5 making it a solution because it makes sense right?

example: (4,6)

6 = 4 + 3

6 = 7

this isn't a solution because six doesn't equal 7
