It could be x > 21 im not sure
Answer:
y=-4x+5
Step-by-step explanation:
the line goes down 4 for every 1 that x changes. the line crosses the y axis at 5.
(this might not be accurate, I can't really see if the line is on the exact point or not)
Statements 2, 3, and 5 are true based on the graph of this function.
