Line-plane intersection

Imagine you have a flat piece of paper (called a plane) with some lines drawn on it. Now imagine you have a string (called a line) that you hold in your hand, and you want to know where it touches the paper.

To find where the string touches the paper, you need to look at where the string and the paper cross paths. Imagine you hold the string up to the paper and slowly lower it down until it touches the paper. Where the string touches the paper is where they cross paths, or intersect.

This is just like finding the intersection point between two roads. Where both roads cross is where they intersect. In the case of a line and a plane, the intersection point is where they touch each other.

Mathematicians use formulas and equations to find the exact point where the line and plane intersect. But the concept is all about finding the point where two things cross paths, just like where two roads meet.
