Question

The point (2,-4) is on the line given by which equation below?

Answer 1

Answer: (A) y=-2x

Explanation:

Lets plug in the point (2,-4) for each equation.

-4=-2(2) this is correct

-4=2*2

-4=4 This cannot be true

-4=-2+3 =-4=1 This is false

Lastly, -4=2-4 this is false because -4 can't equal to -2.

So, A is the answer
