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)

What does the numerator of the slope represent?

• Horizontal change

• Diagonal change

• None of the above

• Vertical change

If the slope is -2/3, how do you move from the y-intercept to plot the next point?

• Up 2, right 3

• Down 2, left 3

• Down 2, right 3

• Up 2, left 3

What does a negative slope indicate about the direction of the line?

• The line is horizontal

• The line goes up from left to right

• The line is vertical

• The line goes down from left to right

How can you plot another point using the slope from an already plotted point?

• Move down and right

• Move up and left

• Move down and left

• Move up and right

What is the y-intercept in the equation y = -2/3x + 3?

• -3

• 0

• 3

• -2/3

What should you do after plotting the y-intercept and additional points?

• Erase the points

• Connect the points to form a line

• Label the points

• None of the above

What is the first step in graphing a linear equation?

• Plot the slope

• Draw the y-axis

• Draw the x-axis

• Plot the y-intercept
