Could I have a push in the right direction? Seems like I have tried all the strategies my math teacher gave me, but I can not get the answer.

I think it’s A and B cause when you look at there sizes

Step-by-step explanation:

First, we need to find the slope.
m = 
m =
m =
m = -2

Next, write the standard line equation:
y = mx + b
Now fill in what you know (pick a coordinate point, it does not matter):
5 = -2(2) + b
Simplify to solve for b:
5 = -4 + b
+4  +4
9 = b

Rewrite the equation:
y = -2x + 9
