Question

Which ordered pair is a solution to the equation? Y=-2x+4
A. (-3, 6)
B. (-4, 5)
C. (5, -6)
D. (-6, 5)

Answer 1

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
