You can put this solution on YOUR website! Which of the ordered pairs
(0, 0), (-2, 10), (-1, -5), (-3, 9)
are solutions for the equation
plug in (x, y)=(0, 0)
 ....left side is equal to right side, so the ordered pair (0, 0)  a solution for the equation
plug in (x, y)=(-2, 10)
 ....left side is  equal to right side, so the ordered pair (-2, 10)  a solution for the equation
plug in (x, y)=(-1, -5)
 ....left side is equal to right side, so the ordered pair (-1, -5) a solution for the equation
plug in (x, y)=(-3, 9)
 ....left side is equal to right side, so the ordered pair (-3, 9) a solution for the equation
