Ok

fisrt we determine sign
negative divided by positive=negative
answer is negative
disregard any signs for now
first convert to from mixed to improper
3 and 1/5=3+1/5=15/5+1/5=16/5

(16/5)/(2/15)
remember the fancy 'invert and multiply'
I won't tell you why because it would take too long, but if you want to know why we invert and multiply, just ask in comments

so, invert an multilply
(a/b)/(c/d)=(ad)/(bc)
(16/5)/(2/15)=(16*15)/(5*2)=(240)/(10)=24

the answer is negative so

-3/7, -8/3 and -5/2,-2 slope
Alja [10]
So the points are (-3/7,-8/3) and (-5/2,-2)
to find the slope do
(y2-y1)/(x2-x1)
(x,y)
x1=-3/7
y1=-8/3
x2=-5/2
y2=-2

subsitute
\frac{-2-( \frac{-8}{3} )}{ \frac{-5}{2} - \frac{-3}{7} }
simplify by finding similar denomenators
\frac{\frac{-6}{3}-( \frac{-8}{3} )}{ \frac{-35}{14} - \frac{-6}{14} }
\frac{\frac{-6}{3}( \frac{8}{3} )}{ \frac{-35}{14} + \frac{6}{14} }
add
\frac{\frac{2}{3}}{ \frac{-29}{14}}
multiply top and bottom by \frac{-14}{29
\frac{\frac{-28}{87}}{1}
\frac{-28}{87}
answer is
slope=\frac{-28}{87}
