Solving Systems of Equations by Graphing

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect.

What is the graphical representation of a linear equation?

Back

The graphical representation of a linear equation is a straight line on a coordinate plane.

How do you find the intersection point of two lines?

Back

To find the intersection point of two lines, solve the equations simultaneously to find the values of the variables that satisfy both equations.

What does it mean if two lines are parallel in a system of equations?

Back

If two lines are parallel, it means they have the same slope and will never intersect, indicating that the system has no solution.

What does it mean if two lines are coincident in a system of equations?

Back

If two lines are coincident, they lie on top of each other, meaning they have infinitely many solutions.
