i forgot the whole process, i know that for the second part since they are parallel they have the same normal its just i guess i use the point they gave me. but i still dont know how to get the scalar eqn with that. and for the first 1 im lost, can some 1 shine light on this please? i need to know ASAP so i can complete my hmwk on vectors.
Determine scalar, vector, and parametric eqns for the plane that passes through the points A(1,-2,0), B(1,-2,2), and C(0,3,2)
Write a scalar eqn for the plane that contains the point (-1,2,0) and is parallel to the plane (x,y,z) = (1,-2,1) + s(3,1,1) + t(4,-2,1)
