In this lesson I will introduce the concept of systems to you. A system is a mathematical way of describing the behavior of something using two or more equations. The subject of systems is HUGE in math so you want to embrace the study of systems by learning the fundamentals in this lesson. Now, the type of system we will study are linear one’s where we use line equations like y=mx + b. Hence, it’s important you know a lot about linear equations to include graphing them. As you will see, the solution to a basic system is the point two lines intersect. You will be graphing lines to find the point of intersection so make sure you have graph paper and a ruler for the lesson.
