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. …

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 …

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.

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. Unit guides are here!

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, …

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

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.

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 …
