Answer
B
Work Step by Step
We first look at the graph and see that the line has a slope of 1/2. A line parallel to this line will have the same slope, so we know that m=1/2. We then put the equation in point slope form:
$y-1=1/2(x+2)$
The answers, however, are all in slope intercept form, so we must isolate y to simplify. Thus, we obtain:
$y-1=1/2 x +1 \\\\ y=1/2x+2$
