I found #m=3/5#

Explanation:

The slope #m# represents the ratio of the change in #y# as #x# changes and gives you the inclination of a line; or:

#m=(Deltay)/(Deltax)=(y_2-y_1)/(x_2-x_1)=(-7-2)/(-8-7)=9/15=3/5#

So, this number tells you that every time #x# increases of one unit then #y# increases of #3/5#.
