Question

Which ordered pair is not a solution of y = 2x + 1?

remember (x, y)

Group of answer choices

(-1, 1)

(3, 7)

(-3, -5)

(0, 1)

Answer 1

So what u wanna do is plug in the values to the equation for example
In (-1,1) (-1 is the x value and 1 the y)
So 1=2(-1)+1
1=-2+1
1=-1 no that’s not the answer because it doesn’t satisfy/or is equal to the y value
(3,7)
7=2(3)+1
7=6+1
7=7 THIS IS THE ANSWER

Hope that helped:)

Answer 2

(-1,1)

Explanation:

All you have to do is plug it in the equation:

(x,y)

For (-1,1)

1=2(-1)+1

Simplify:

1=-1 but you know that 1≠-1 so (-1,1) is not it

For (3,7)

7=2(3)+1

Simplify:

7=7

For (-3,-5)

-5=2(-3)+1

-5=-5

Simplify:

For (0,1)

1=2(0)+1

1=1
