Answer: Choice B. slope = -1/2, y intercept = 1
=======================================================
Explanation:
The line goes downhill as we move from left to right. This means the slope is negative. We can rule out anything that has a positive slope. The answer is between A and B.
We can rule out choice A because the y intercept is actually 1 (not 2) because it crosses the y axis here. The only thing left is choice B.
The slope is -1/2 because moving from (0,1) to (2,0) means we move down 1 unit and over to the right 2 units.
slope = rise/run = -1/2
rise = -1 indicates a drop of 1
run = 2 means we move to the right 2 units

You can use the slope formula to get the same result
I'll use the two points (0,1) and (2,0)
m = (y2 - y1)/(x2 - x1)
m = (0 - 1)/(2 - 0)
m = -1/2
You could use any other two points you want as long as they are on the diagonal line.
