Graphing Lines with Slope and y-Intercept

What are the two key components needed to graph a linear equation?

• Slope and x-intercept

• Slope and y-intercept

• Y-intercept and x-coordinate

• X-intercept and y-coordinate

Which axis does the y-intercept lie on?

• Y-axis

• Z-axis

• None of the above

• X-axis

If the y-intercept (b) is 3, where should you place the first point on the graph?

• (0, -3)

• (-3, 0)

• (3, 0)

• (0, 3)
