I do hope I helped you in a way! If I am incorrect I apologize.
The angle of depression is
tan^-1 3/7 = 23.2 deg
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).
Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2
Slope is 2.
