Question

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

Answer 1

Answer:

(-2,6)

Step-by-step 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:

$x+\frac{1}{2}y\\=(-2)+\frac{1}{2}(6)\\=-2+3\\=1$

This is right.

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