This week I learned about slope and Parallel, Perpendicular lines.

I’ll focus on Parallel and Perpendicular lines this week’s blog.

First, Parallel line is the line if they have the same slope such as m1=m2

A perpendicular line is a line if the product of the slope is -1

ex) m1× m2 = -1       m1= -1/m2

Here is an example of a graph.
