Question

Which of the following orderd pairs is a solution of x + 1/2 y = 1​

(-2,6)
(2,-6)
(-2,-6)

Answer 1

(-2,6)

Explanation:

For an ordered pair (x,y) to be a solution to the equation given, we have to plug in x-coordinate in "x" and y-coordinate in "y" of the following equation and see if it is "1".

Whichever makes it true, is the correct answer.

Checking:

`x+(1)/(2)y\\=(-2)+(1)/(2)(6)\\=-2+3\\=1`

This is right.

We don't need to check the other two, the first one is the right option.
