Answer:
Remember that to find slope you need to do rise/run, in which rise is movement up and down, and run is movement left and right.
Also, don't forget to start at the left-most point and count the units to the next point.
Additionally, if the line is going upwards to the right then it's a positive slope, and when it goes downwards to the right it's negative.
Coordinates are presented in (x,y) form.
(Keep these tips in mind for each question.)
1) Slope = -1/3
Point 1 = (-1,-1)
Point 2 = (2,-2)
2) Slope = 3
Point 1 = (-1,-4)
Point 2 = (0,-1)
3) Slope = -3/2
Point 1 = (-4,0)
Point 2 = (-2,-3)
4) Slope = 3/2
Point 1 = (0,-3)
Point 2 = (2,0)
5) Slope = 5/3
Point 1 = (-4,-3)
Point 2 = (-1,2)
6) Slope = 7/3
Point 1 = (1,-4)
Point 2 = (4,3)
7) Slope = -6/2 simplified is -3
Point 1 = (1,2)
Point 2 = (3,-4)
8) Slope = 7/3
Point 1 = (-3,-4)
Point 2 = (0,3)
Hope this helps :)
