Answer:
A and C
Step-by-step explanation:
To determine which of the following satisfies the function y = -3x + 4, plug in the values of (x, y) of each options given into the equation.
Option A: (x, y) = (4, -8)
-8 = -3(4) + 4
-8 = -12 + 4
-8 = -8 (true)
Therefore, (4, -8) satisfies the function given.
Option B: (x, y) = (2, -10)
-10 = -3(2) + 4
-10 = -6 + 4
-10 = -2 (not true)
Therefore, (2, -10) DOES NOT satisfies the function given.
Option C: (x, y) = (-1, 7)
7 = -3(-1) + 4
7 = 3 + 4
7 = 7 (true)
Therefore, (-1, 7) satisfies the function given.
Option D: (x, y) = (-3, 4)
4 = -3(-3) + 4
4 = 9 + 4
4 = 13 (NOT true)
Therefore, (-3, 4) DOES NOT satisfies the function given.
