Exploring Adding and Subtracting Rational Expressions

What is the main goal when graphing systems of equations?

• To calculate the x-intercept of each line

• To find the point of intersection

• To determine the y-intercept of each line

• To find the slope of each line

What form should an equation be in to easily graph it?

• Standard form

• Quadratic form

• Slope-intercept form

• Point-slope form
