Question

Which of the points below satisfies the inequality in the box? check all that apply. y>= -3x+2

A.(-1,10)

B.(1,-2)

C.(0,2)

D.(0,-1)

E.(2,7)

F.(2,1)

Answer 1

y ≥ -3x + 2

It will be good to draw a graph and read the solution from the graph

y = -3x + 2

for x = 0 → y = -3 · 0 + 2 = 2 → (0, 2)
for x = 2 → y = -3 · 2 + 2 = -6 + 2 = -4 → (2, -4)
Answer: A, C, E, F.
