When solving systems of linear equations, one method is to graph both equations on the same coordinate plane. The intersection of the two lines represents a solution that satisfies both equations.

Let's remember how the graphical approach to solving a system of equations works. Below are the lines corresponding to the equations in the following system.

Walk through examples of solving systems of equations by finding the point of intersection. We can find the solution to a system of equations by graphing the equations. Let's do this with the following …

To solve a system of linear equations by graphing, you need to graph each equation separately. Find two points on each line and connect them. The point where the two lines intersect is the solution to …

Estimate the solution to the system of equations. You can use the interactive graph below to find the solution.

Remember, the solution to a system of equations is the values of the variables that meet both equations. When you graph an equation, you're showing the points - pairs of (x, y) values that meet the equation.

Some equations are hard to solve exactly with algebraic tools. We can always solve an equation by graphing it, although the solution might not be exact. This is an example of how to solve a relatively …

How can you use clues from two algebraic expressions to figure out the value of a variable? In this unit, you'll learn how to solve a system of equations or inequalities in two variables by elimination, …

If one line is useful, let's see what we can do with two lines. In this unit, we learn how to write systems of equations, solve those systems, and interpret what those solutions mean in a real-world context.
