Hello there! Slope is rise/run. The formula for finding slope is y2 - y1/ x2 - x1, meaning that you subtract the first x and y-coordinates from the second x and y-coordinates. We'll use the points (0, 3) and (3, 2) for this case. Plug in the values into the formula to get this:
2 - 3 / 3 - 0
Subtract the values in order to get -1/3. There. The slope of the line is -1/3.
If you add all the numbers on the right together you get -35 then you divide by 5 which gives you the average of -7*F

The measurement of angle ABC is
B) 217 1/2
Hope this helps...
I believe #7 is D) 5.5 x W
