Question

its asking ordered pairs to be put in this is impossible

Answer 1

Set x equal to the x-value in the ordered pair and if it equals the y-value of that same ordered pair, then it is a solution.

Answer 2

howwww???

Answer 3

For example: If you have the ordered pair (2, 7) and the equation y=5x+4,
you would replace the x with the x-coordinate, 2, and the y with the y-coordinate, 7.
You would end up with 7=5(2)+4 or 7=14. Well, 7≠14 so it is not a solution. However, take the ordered pair (-2,-6) and do the same. -6=5(-2)+4. You get -6=-6. The ordered pair (-2,-6) IS part of the solution.
