Question: Does (-1,8) make the equation y= -8x true?
Answer:
Yes!
Explanation: You just need to plug in the values. The equation is y = -8x and we want to know if (-1, 8) is a point on the line. So, you take (-1, 8) and plug it into the equation. 8 = -8(-1)
A negative times a negative equals a positive. So -8*-1 = 8
(-1, 8) would make the equation true.
