.

the line "l" passes through the point P=(1,-1,1) and has a direction vector d=[2,3,-1], for the following plane Pl, determine whether l and P is parallel, perpendicular, or neither.

a) 2x + 3y - z = 1

could you tell me also how it would differ if it was parallel or neither or perpendicular?

Thank You!!
