9. Find the scalar equation of the line with normal F: = (_ 391) passing through 13(413) 10. Find the vector equation of the line perpendicular to 2x _ 3y + 9 = 0 and passing through the Y intercept or x = 4 + k y = 3 2k . 3x y + 7 = 0 P(2,3)' 1 1. Find the scalar equation of the line perpendicular to passing through 12. Do these represent the same line? How are the lines related ( parallel, identical, perpendicular,etc) If, : (x,y)= (-1,3)+t(2,4) E, :(x,y)= ( l,4)+t(1,4) a) 2:2x+y1=0 b)2:4x+y3=0
