The vertex form let’s you find the vertex. The factored form gives you the roots.
If I missed anything please tell me
In the fundamental counting principle, you are multiplying to get the total number of possibilities as a result. For example, if you have 5 different types of bread, 8 types of cheese, and 6 types of meat, you have 240 choices (8 x 6 x 5).

Here we have the following points:

The point-slope form of the equation of a line is:

So the slope can be found as:

So:

So the equation is finally:

This line passes through and is shown below.
