Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
96 degrees is your answer
supplementary means the angles add up to be 180 degrees. if 1 angle is 84 degrees then 180-84=96
