Which ordered pair is a solution of the equation y+5=2 (x+1)

options

5,10

-1, - 5

5,10 and - 1,-5

neither

Anwser: (-1,-5)

Why:

All you have to do is plug in the coordinates into the equation ...

(5,10):

10+5=2 (5+1)

15=10+2

15=12

This is false so this ordered pair isn't a solution

(-1,-5):

-5+5=2 (-1+1)

0=-2+2

0=0

This statement is true therefore this ordered pair is a solution and is the only solution.
