3. Which ordered pair is a solution of the equation y = x - 2 ? A. (3, 1)
B. (1, 3)
C. (- 1, 3);
D. (3, - 1)

A. (3,1)

Step-by-step explanation:

y=x-2

Putting A. (3,1) in the above equation,

y=3-2=1

so, if x=3, y will be 1 which satisfies the equation

A) (3, 1)

Step-by-step explanation:

Because (x, y)=(3, 1).

Now plug in those values into the equation y=x-2.

You get 3-2=1, which is the correct y-value.
