Understanding Graphing Equations

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

• Plot the y-intercept

• Draw a vertical line

• Calculate the midpoint

• Identify the x-intercept

How do you use slope to graph an equation?

• Plot x-intercept

• Plot y-intercept

• Calculate the midpoint

• To move to plotting the next point

How do you find the slope in standard form?

• -B/A

• B/A

• -A/B

• A/B

What is the y-intercept if C is 21 and B is 3 in standard form?

• 21

• 1

• 3

• 7

In point-slope form, what should you do after plotting the given point?

• Draw a horizontal line

• Calculate the midpoint

• Use the slope to plot the next point

• Find the x-intercept
