Question

Is (0,3) a solution to the equation y=x+3?

Answer 1

1. To find out if (0,3) is a solution to y = x +3 you replace x and y with (0,3)

y = x + 3
3 = 0 + 3
3 = 3        Correct

The answer is YES


2. To find out if (1,-4) is a solution to y = -2x you replace x and y with (1,-4)

y = -2x
-4 = -2(1)
-4 = -2        Incorrect

The answer is NO
