Explanation / Answer

ANSWER

3) A point vector on the line: (3,4,5)

A direction vector: ( i + 2j ) cross product ( j - k ) = (1,1,0) cross product ( 0,1,-1 )

=( -i + j + k )

vector equation:r(t)=( 3,4,5) + t( -1,1,1)

=(3-t , 4+t ,5+t )

parametric form: x=3-t , y=4+t , z=5+t

ANSWER

2) we have two given points (1,2,3) and (2,5,-2)

then the direction vector is ( 2-1, 5-2, -2-3) = (1, 3, -5)

hence,the equation of the line is ( i+3j -5k )

vector form is (2,5,-2 )+ t(1,3,-5) = ( 2+t, 5+3t, -2-5t )

parametric form:   x=2+t , y=5+3t , z=-2-5t
