In this question, we are asked to find vector and parametric equations of the line through the point p are orthogonal to the given plane.
00:09
And this is a setup.
00:10
This is a plane and the line is orthogonal and somewhere here is the point p.
00:20
And the line is orthogonal to the plane.
00:23
It goes through the point and is orthogonal to the plane.
00:36
So, and this is a point p.
00:43
And any plane has a normal vector.
00:49
A normal vector is any vector perpendicular to the plane.
00:53
So our plane also has a normal vector, and it's easy to find the coordinates of the normal vector.
01:03
They are just the coefficients in front of x, y, and z in the equation of the plane.
01:11
And since there is no y in the equation, we simply need to assume that it's like plus y, 0 times y.
01:21
So the coefficient in front of y is 0...
