What do I have to know to solve a system of equations by graphing

This video tutorial covers the essentials of solving systems of equations by graphing. It emphasizes the importance of graphing in slope-intercept form as the preferred method and discusses converting standard form equations to slope-intercept form. The tutorial also highlights the ability to identify parallel and perpendicular lines by inspection, which helps determine the type of solution a system has. Additionally, it introduces the concepts of consistent and inconsistent systems, as well as independent and dependent solutions. The video concludes with a summary of the key points necessary for successfully solving systems by graphing.

What is the preferred method for graphing when solving systems of equations?

• Using the midpoint formula

• Using the quadratic formula

• Graphing in slope-intercept form

• Graphing in polar coordinates

How can you identify that two lines are parallel by inspection?

• They have the same slope

• They intersect at one point

• They have different slopes

• They form a right angle

What does it mean if two lines are perpendicular?

• They never intersect

• They have no slope

• They intersect at exactly one point

• They are the same line

What type of system has no solutions?

• Independent

• Inconsistent

• Dependent

• Consistent

What is the main goal when graphing systems of equations?

• To find the midpoint of the lines

• To calculate the area between the lines

• To find where the lines intersect

• To determine the slope of each line
