Question

Which of the points is not a solution to x-2y=4 and my answers are(0,-2) , (0,2) , (2,-1), (4,0)

Answer 1

B and D are not solutions..

Answer 2

Plug each point into the equation and see if they're true. For example, take (0, -2) and plug it in like this: 0-2(-2)=4 --> 4=4, so (0, -2) is a solution.
