When we talk about two lines that are perpendicular, we mean they cross each other at a right angle.
These lines have a special relationship when it comes to their slopes.
The slope is basically a number that shows how steep a line is.
If one line has a slope called (m_1), the other line, which is perpendicular to the first, has a slope called (m_2).
Here's the important part:
You can find the slope of the perpendicular line using this formula:
[ m_1 \cdot m_2 = -1 ]
What does that mean?
It means that the slope of one line is the negative opposite of the other line's slope.
Let’s look at a couple of examples:
Understanding this idea is really important.
It helps you when you're making graphs and solving problems that involve perpendicular lines!
