Question

Does the point (-1, -3) satisfy the equation y = x + -2?

Answer 1

To do this, we plug -1 in as x and -3 in as y. If the two sides are equal, (-1, -3) would satisfy y = x + -2. If they aren't equal, it doesn't satisfy the equation. We get:
-3 ? -1 + (-2);
and so,
-3 does indeed equal -3.
Thus, the point (-1, -3) satisfies the equation y = x + -2
