Question

if y = x-3 , which ordered pair is NOT a solution to the equation y=x-3

a. (2,-1)
b. (-3,-6)
c. (3,0)
d. (-4,-6)

You simply plug in [x, y] values into the equation. For example,
y = x - 3 
a. (2, -1)
-1 = 2 - 3
-1 = -1

So we know that a is an ordered pair. Now you try out for the rest.

Choice (D) does not satisfy that equation becuase when x = -4 and y = -6,
- 6 does not equal to -4 -3
-6 does not equal to - 7.

Easyaspi314 has already given you the answer. Though, what good is the answer if you don't know how to do it yourself? You simply plug in values for x and y into the equation and if it does not equal, then it is not an ordered pair.
