Question 121533
All you have to do is plug in the x values for x and the y values for y and see if you get the same number. <br>

y = -2x+5 (3,-5)
-5 = -2(3)+5
-5 = -6+5
-5 = -1 nope this is not a solution because -5 does not = -1. <br>

y = -2x+5 (2.5,0)
0 = -2(2.5)+5
0 = -5 + 5
0 = 0 yes this is a solution, because 0 does equal 0.
