For the first one the slope is 0 because to have a slope the y must be rising, but here it is staying the same level so it is just 0.
The second one rises by .6 and goes right by 8 which is .6/8 which is equivalent to the fraction 3/40. However on the grid it goes up 1 and right 2 for each point so it could be 1/2, but I am sure of the first one.
