Question 342261: Is (-1,2) a solution of y=1/2 x - 1?
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! Replace x with -1 and y with 2.
If you get the same answer on both sides of the equation, then the given point is a solution to the given equation.
2 = (1/2)(-1) - 1
2 = -1/2 - 1
2 = -3/2
As you can, we get two different answers on both sides of the equation.
We can now say that the given point (-1,2) is not a solution of the equation.
In other words, the point (-1,2) does not lie on the graph of your equation.
