When we are faced with a quadratic that is not “nice” to factor we need to find a way to factor it. This is where the quadratic formula comes in. The discriminant is a value that can be calculated for each quadratic equation. Depending on the value of the discriminant, we can determine if the quadratic equation has a solution, or has factors, or not.

The distance between a point and line is given by the shortest distance which is the perpendicular distance between the two. Learn more about what this is and how to find this distance.
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.
