# Help with linear equations and graphing

Graphing equations is the heart of Algebra. Especially graphing linear equations, which will be the focus of this unit. This meeting place is called the Point of Intersection. If you have a linear equation and a quadratic equation on the same xy-plane, there may be TWO POINTS where the graph of each equation will meet or intersect. Visa and MasterCard security codes are located on the back of card and are typically a separate group of 3 digits to the right of the signature strip.American Express security codes are help with linear equations and graphing digits located on aand front of the card and usually towards the right.

Graphing Linear EquationsNow that we havesolved equations in one variable, we will now work on solving equationsin two variables and graphing equations on the coordinate plane. This is often dith the coordinateplane is called the Cartesian plane, or graph. When working with equations in morethan one variable, using the Cartesian graph ca.
