The formula for slope is
%28Y2-Y1%29%2F%28X2-X1%29
Put in the information you know. remember coordinates are of the form (X,Y). We get
3-0/4-%28-3%29, be very careful about negative signs.
3%2F7
This is choice [ D ]

slope (m) is the difference in rise (y) over the difference in run(x)
(y1-y2)/(x1-x2)=m
(0-3)/(-3-4)=m
-3/-7=3/7=m
answer D) 3/7
