Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality 
follows that A lies on the line.
B: x=3, y=13, then from the equality 
follows that B lies on the line.
C: x=8, y=2, then from the inequality 
follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality 
follows that D lies on the line.
Answer:
f(4) = -11
Step-by-step explanation:
Plug in 4 for x: Note that x = 4.
f(x) = -2x - 3
f(4) = -2(4) - 3
Remember to follow PEMDAS. First, solve the multiplication, then subtract:
f(4) = (-2 * 4) - 3
f(4) = (-8) - 3
f(4) = -11
f(4) = -11 is your answer.
