Homework Help: Math: Scalar Equations of a Plane

Posted by Anonymous on Thursday, March 27, 2008 at 11:12pm.

Find the scalar equation of each of the following planes. State which of the planes, if any, are coincident.

a) r = (-8,-1,8) + s(-5,1,4) + t(3,2,-4)
Scalar Equation: -12x - 8y - 13z = 0

----

b) r = (-2,-2,5) + s(3,1,-1) + t(4,1,-4)
Scalar Equation: -3x + 8y - z + 15 = 0
