Question

Example: y = -2x and y = x + 3 2)

Does the point (2, 5) make either equation true? Explain.

Answer 1

For the point (2,5), 2 = x and 5 = y.
5= -2(2)
5 = -4
So no, the first one y=-2x would not work since -4 is not equal to 5.
5=2+3
5=5
Yes, that second one y=x+3 does work since 5 is equal to 5.
