Hi can you please help me with this question step by step thank you

1. Determine the scalar equation of the plane containing the point (-1, 1, 0) and perpendicular to the line joining the points {1, 2, 1} and (3, -2, O). 2. a} Explain why the equation F = [1,0, 1] + s[2, 3, 4] + t[4, 6, 8], s, t E R, does not represent the equation of a plane. Change one number in the equation to make it a plane and explain how this change now gives a plane. 13} What do the s and t in the equation of a plane represent? Use your newly formed equation to support your explanation. These are communication question. Be sure to include enough detail to justify full marks
