Question

Is (-1,2) a solution to the following linear equation:
2x + y = 2

Answer 1

No

Explanation:

plug in the variables into the equation

(x,y)

(-1,2)

2(-1)+2=2

2*-1=-2

-2+2=0

2 does not equal 0 so therefore no, it is not a solution

Answer 2

Plug in the values
2(-1) + 2 = 2
-2 + 2 = 2
0 = 2, false

(-1,2) is not a solution
