When finding the slope of a line passing through 2 points
we can use the slope formula.
m+=+%28y2-y1%29%2F%28x2-x1%29
Lets use point (7,3) as (x1,y1) and point(9,-2) as (x2,y2).
So...
m+=+%28-2-3%29%2F%289-7%29
Then subtract...
m+=+%28-5%29%2F%282%29
So the answer is D)-%285%2F2%29
Thanks for the question
Good Luck!
