ok so looks like point slope form
y-y1=m(x-x1)
when
slope=m
and a given point=(x1,y1)
first of all
the points (12,3) and (6,1) are there
y-3=m(x-12) or y-1=m(x-6) should be them
not A or D, eliminate them
teh last thing is the slope
find slope
either 3 or 1/3
slope betwen points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1)
(6,1) and (12,3)
slope=(3-1)/(12-6)=2/6=1/3
slope is 1/3
out of B and C. C has slope of 1/3
answer is C
