Graphing Linear Equations
The coordinate plane is a two-dimensional surface on which we can plot points, lines and curves. It has two scales, called the x-axis and y-axis, at right angles to each other that meet at the point of origin (0, 0). Rather than teaching graphing equations using the coordinate plane in an abstract format, students are given real-life examples of how and why they could create and use a line to give them information that will help them to solve problems.
