L1: r(t)= (-5 + 3t)i + (1+t)j

L2= r(s) = (1+2s)i + (5-6s)j

I know they are perpendicular,

and the system of equations I think is

t= 4/5

s =8/5

so how do I find the point of intersection

- math ASAP -

By equating the scalors of the i and j components to solve simultaneous equations in t and s:

-5 + 3t = 1 + 2s

1 + t = 5 - 6s
