Explain.A (2,B (0,C (1,D (4,E (3,......
I have no idea how to answer this! :( Please help me! How would you answer it?

Four of the five points below are solutions of the same linear equation. Which is not? Explain.

A (2,1)
B (0,-4)
C (1,-2)
D (4,4)
E (3,2)

It's A, (2,1).

You can figure it out by actually going ahead and plotting all the points on a graph. You'll see that all other points except for (2,1) go on to form a straight line.

A, i found this by just finding the slopes of the lines (y1-y2)/(x1-x2) and finding the slope that was not equal or opposite to the rest.
