Answer:
5/3
Step-by-step explanation:
To find the slope we pick one set of points
2/3,-1/2
Set your equation up like this
y2-y1/x2-x1
Plug in and subtract(notice the negative)
And we get 5/3
Hope this helps
They are proportional, since in 5/6 if you multiply both the numerator and denominator by 3, you get 15/18.
