You can put this solution on YOUR website! (1)(3,-4) 5x-2y=17========NO
5x+-2y+2y=17+2y
5x+0=17+2y
5x=17+2y
x=3.4+0.4y
(2)no (3) no (4)yes (5)no
(6)no (7)no (8) no
OK, NOW I ONLY WORKED OUT THE FIRST PROBLEM
YOU SHOULD BE ABLE TO LOOK AT THIS EXAMPLE

Sub 3 for x, and -4 for y and see if it's equal.
5x-2y=17
5*3 - 2*(-4) =? 17
15 + 8 =? 17
23 =? 17
Not equal, so not a solution.
