find the slope, if it exists, of the line containing the pair of points
(9,5) and (10,3)
teh slope m= 1.2
m=(3+9)/ (105)
m=6/5
m=1.2

Sorry, your answer is not correct. It is a big negative number.
The slope of a line passing between two points P1(x1,y1) and P2(x2,y2) is
m=(y2y1)/(x2x1) provided (x2x1)≠0
I leave it to you to recalculate the slope required. Post your answer for verification if required.

M= (y2y1)/(x2x1)
so (35)/(109)=7

For 35 I get 8.
