The answer is D. Trust me.
first, the slope is needed, which is 3-2/3--3 which is 1/6 and so this will be y=(1/6)x+b which then we'll input (3,3) which is 3=2+b or b=1 so the equation is y=(1/6)x+1
The answer is B. 13.9. Since M is the midpoint, it splits the line into 2 equal parts.
27.8 / 2 = 13.9
