Solving Systems of Linear Equations

A system of linear equations is...

• a set of two or more linear equations in the same variables
• a polynomial with three terms
• set of two or more quadratic equations in the same variables

The solution to a system of linear equations is...

• the slope of the line
• the y-intercept
• the point where the lines intersect

• the rise over run
