Answer :
Answer:
4/5
Step-by-step explanation:
you need to to use the the point slope formula which is m=y2-y1/x2-x1.
so you plug in 9--3/5--10 so as you know negative and negative equals positive so it would be 9+3/5+10 and it would equal 12/15. So you simplify it by dividing it by 3 which will equal to 4/5.
