Math Help - A set of parametric equations
1. A set of parametric equations
Find a set of parametric equations for the line through the point
P(2,1, 0) which is perpendicular
to the plane described by the general equation
x + z = 2.
ok so that's how i did
-1i + 0j + 1k = 2
x = 2 - k
y = -1
z = k
Is it correct?
