Answer:
B y = -1/2x + 7/2
Step-by-step explanation:
We know that it has a negative slope since the points go from the top left to the bottom right
We can eliminate A and D
The y intercept is where it crosses the y axis
It should cross somewhere between 2 and 4
C  has a y intercept of 9 which is too big
Lets verify with a point
x = -4
y = -4(-4)+9 = 16+9 = 25  (-4,25)  not even close to being near the points on the graph
checking B
y = -1/2 (-4) +7/2
   = 2 + 7/2 = 11/2 = 5.5  it seems  reasonable
