Exploring Adding and Subtracting Rational Expressions

What is the main advantage of using slope-intercept form for graphing linear functions?

• It is faster to compute.

• It is more accurate.

• It eliminates the need for tables.

• It requires less calculation.

What is the first step in graphing a linear function using slope-intercept form?

• Calculate the slope.

• Draw the x-axis.

• Graph the y-intercept.

• Create a table of values.

How do you use the slope to create more points on the graph?

• By drawing a horizontal line.

• By using a calculator.

• By counting the rise over run.

• By estimating the points.

What can be used as a straightedge if a ruler is not available?

• A bookmark

• A piece of paper

• A pencil

• A piece of string

In the example with a slope of 2/3, what are the two possible directions to plot the points?

• Up 3, right 2 or down 3, left 2

• Up 3, left 2 or down 3, right 2

• Up 2, right 3 or down 2, left 3

• Up 2, left 3 or down 2, right 3

When graphing a line with a slope of -3, what is the correct rise over run?

• Up 3, right 1

• Down 3, right 1

• Up 3, left 1

• Down 3, left 1

For a slope of 1, how can it be represented as a fraction?

• 1/1

• 1/2

• 2/1

• 1/3

How should you handle a slope that is a fraction, such as -1/5?

• Only one number should be negative.

• Ignore the fraction.

• Both numbers should be negative.

• Treat both numbers as positive.

What should you check to ensure your graph is accurate?

• The graph should be a zigzag.

• The graph should have no points.

• The graph should be a curve.

• The graph should be a straight line.

What is the final step after plotting all points on the graph?

• Erase the points.

• Label the points.

• Draw a curve through the points.

• Connect the points with a straight line and add arrowheads.
