That will be the equation of a plane.

这就是这个平面的方程了。

So, remember, in the linear system, you can think of a linear system as asking you to find the intersection between three planes because each equation is the equation of a plane.

记住，线性方程组问题，可以理解为求三个平面的交，因为每个方程就是一个平面。

So, in fact, you know, when you plug in these things, normally you get a quantity that's of a form, something times t plus a constant because that's what you plug into the equation of a plane.

事实上，代入这些之后，通常可以得到这种形式的值，有时候是t加上一个常数，因为这是你代入平面方程的。
