Consider the following planes. 3x − 2y + z = 1, 2x + y − 3z = 3
prisoha [69]

Solve for any of the variables; for instance, z:

z=1-3x+2y

z=-\dfrac{3-2x-y}3

Then

1-3x+2y=-\dfrac{3-2x-y}3\implies11x-5y=6\implies\begin{cases}y=\frac{11x-6}5\\z=1-3x+\frac{22x-12}5\end{cases}

Let x=t; then the intersection is given by the vector-valued function

\vec r(t)=\left(t,\dfrac{11t-6}5,1-3t+\dfrac{22t-12}5\right)

or

\vec r(t)=\left(t,\dfrac{11t-6}5,\dfrac{7t-7}5\right)

KATRIN_1 [288]

C = 200p + 400

Because C is the cost of a given day, 400 acts as a y-intercept.

400 is the initial fee paid then 200 per each phone manifactured, meaning that 200 is the slope.
