Question

Which ordered pair is a solution of the equation y=x-2

A. (3,1)
B. (1,3)
C. (-1,3)
D. (3,-1)

Answer 1

A. (3 , 1)

Explanation:

Note the placement of x and y for points:

(x , y)

Plug in the corresponding numbers for the corresponding variables:

(x , y) = (3 , 1)

y = x - 2

(1) = (3) - 2

1 = 3 - 2

1 = 1 (True).

A. (3 , 1) is your answer.
