Consider two coordinate axes i.e X and Y.
Taking the altitude as Y Axes and horizontal distance as X Axes
Then we get the following points on X Axes as (`13000,0) and on Y axes as (0,600).
[tex]So, to find the slope of two points (x,y) & (p,q)
we use the formula= y -q/x-p
so slope of (13000,0) and (0,600) = 600 - 0/0-13000 =600/-13000
= 6/-130 = -3/65[/tex]
