The answer is B.
Slope-intercept line is written as:
y=mx+b
m=slope
b=y-intercept
4 is the y-intercept because the line crosses the y-axis at 4.
The slope is -2 over 5, because slope is written as y over x.
So, if you start at the point at the 4, count 2 spaces down and 5 spaces right. The line crosses the point exactly, which is how you know the slope is accurate.
