Question Number 39899 by Rio Mike last updated on 13/Jul/18
Given the lines   l_1 ; 3y = 2x ,l_2 ; y = −((3x)/2) + p  and l_3 ; y ^ = x + 1  a) find the value of p if   the point of intersection between  l_1  and l_2  is (3,5)  b) find the cosine of the angle  between l_2  and l_3   c) which line holds the point  (1,2).  d)find the line l_4  with gradient  ∫_4 ^π [l_1  + l_2  dx] perpendicur to  l_2 ,parrallel to l_1 .
