Question

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

Answer 1

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.
