The vector equation of a line is another form of interpreting a line but now with a different structure called a vector. Again, we will see a parameter in this form. A single parameter indicating that we are representing a linear relationship.

Another form of interpreting the linear relation is with the parametric equation of a line. In this form we have an unknown or parameter value. Depending on how many parameters there are we determine the type of “plane” we have. In our case here we will see one parameter indicating that we have a line.
The scalar equation of a line is another way to represent a linear relationship. Learn more about the scalar form of the equation of a line and practice writing the scalar equation form of a line.
Given two points it may be necessary to find the midpoint of the line between the two points. Learn about the midpoint formula for finding the midpoint of a line segment.
What is a linear system of equation? And how do you solve a linear system of equation? We will answer both of these questions and give you some exercises to practice on.
There is more than one way to write the equation of a line in the Cartesian plane. Learn the different ways. Practice writing the equation of a line in different ways.
