Retest: Graphing Systems of Equations

Front

What is a system of linear equations?

Back

A set of two or more linear equations with the same variables.

Front

What does the solution of a system of equations represent?

Back

The point(s) where the graphs of the equations intersect.

Front

How can you determine if a system of equations has no solution?

Back

If the lines are parallel and never intersect.

Front

What is the graphical representation of a linear equation?

Back

A straight line on a coordinate plane.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The equations represent the same line, so every point on the line is a solution.

Front

What is the slope-intercept form of a linear equation?

Back

Front

How do you find the y-intercept of a linear equation?

Back

Front

Back

The point of intersection is (2, 0).

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.

Front

How can you solve a system of equations graphically?

Back

By plotting the equations on a graph and identifying the intersection point.
