On line

On line p: x = 4 + t, y = 3 + 2t, t is R, find point C, which has the same distance from points A [1,2] and B [-1,0].

Correct result:

x =  2
y =  -2

Solution:

x=4+t y=3+2t  (4+t1)2+(3+2 t2)2=(4+t(1))2+(3+2 t0)2  12t=24  12 t=24  12t=24  t=2  x=4+t=4+(2)=2
y=3+2 t=3+2 (2)=1=2



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
