Which ordered pair is a solution to the equation? y=-2x+4
a. (-3, 6)
b. (-4, 5)
c. (5, -6)
d. (-6, 5)

To find that out, we need to substitute the values of each pair and see which makes the equation true:
y = -2x + 4
and the answer is C. (5, -6), lets substitute:
-6 = -2(5) + 4
-6 = -10 + 4
-6 = -6
which holds true
