I could use some help with the following problem Thank you

Let F = ri+(x+y)j+ (x - y+ z) k. Let the line I bex = 1 - 3t, y = - (1 + 5t), z = 4t - 3. (a) Find a point P = (co, yo, 20) where F is parallel to I. P Find a point Q = ($1, 31, 21) at which F and I are perpendicular. Q Give an equation for the set of all points at which F and / are perpendicular. equation
