Question

is (1,-4) a solution to the equation y=-2x

Answer 1

No, the solution to the equation would have to have an x value, the first term in the parentheses, have the value of the y value, the second term in the parentheses.

Answer 2

To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer.
