That's the normal to the plane right? How do you find it?find normal (n hat) by doing cross product with the direction of line l and the directon vector A.
replace in the formula r. n hat = a . n hat
a can be the point in line equation (4,-2,2)
replace n u get the answer.
Yeah what's the general equation for it? Is it the cross product of the position vector of any point on a plane and the direction vector? Isn't the direction of line l the same as the direction vector A?cross product of direction of line n direction vector A
i mentioned it there
