Parametric form

Calculate the distance of point A [2,1] from the line p:
X = -1 + 3 t
Y = 5-4 t
Line p has a parametric form of the line equation. ..

Correct result:

x =  0.2

Solution:

p: x=1+3t y=54t  A[2,1]=A[m,n] m=2 n=1  qp:ax+by+c=0 a=4 b=3 q:4x+3y+c=0   4 (1)+3 5+c=0  c=11   x=a m+a n+ca2+b2=4 2+4 1+(11)42+32=15=0.2
