In an ordered pair, x is the first number and y is the second number. So this is telling you x=1 and y=-5. You can take this information and plug it into the formulas.

x + 2y = -9
1 + 2(-5) = -9
1 + -10 = -9? True

x - y = 6
1 - -5 = 6?
1 + 5 = 6? True.

(Subtracting a negative makes it a positive.)
