Question

Which ordered pair is not a solution of the linear equation shown?

1
y=-x
2
OA) (2, 1)
B) (1.-—-)
1,
2
OC) (4,8)
OD) (-2,-1)

Answer 1

C : (4,8)

Explanation:

The equation y = (1/2) x

Or, 2y = x ==> x = 2y
means that, for any value of x, the y value must be one-half that value or, in other words, for any value of y, x must be twice the value of y

A, B and D will satisfy the above equation if you plug in values of x and y given

In C we have x = 4 and y =8 so x = y/2 NOT 2y
