and its -1/2. Already we can fill in the equation to be Y equals -1/2 X plus B.

Well the question gives us one point the line is going to intersect

and we know that the slope is gonna be gently negatively sloping

at minus a half. So rewrite the equation to be one equals -1/2

times 3/4 plus B. Then just solve and we have one

equals -3/8 plus B. Add 3/8 to both sides

and we have 1 3/8 equals B. Glance at the potential answers and we see that there

is no 1 3/8, but there is an 11/8.

So that's the form they want this thing in and now we can write the equation as

Y equals -1/2 X plus 11/8 and the answer is D.
