Graphing Lines with Slope Intercept Form

The video tutorial introduces the slope-intercept form of a line, y = mx + b, explaining its components: the slope (m) and the Y-intercept (b). It demonstrates how to graph a line using this form by plotting the Y-intercept and using the slope to find another point. The tutorial also highlights common mistakes, such as starting from the origin instead of the Y-intercept, and provides additional examples for practice.

What does the 'm' represent in the slope-intercept form y = mx + b?

• The y-intercept

• The x-intercept

• The constant term

• The slope

In the equation y = mx + b, what does 'b' stand for?

• The slope

• The origin

• The x-intercept

• The y-intercept

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

• Plotting the x-intercept

• Drawing the line

• Calculating the slope

• Plotting the y-intercept

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

• Up 2 units, right 3 units

• Down 3 units, left 2 units

• Down 2 units, left 3 units

• Up 3 units, right 2 units

What should you do after plotting the y-intercept and the next point using the slope?

• Calculate the x-intercept

• Draw a line through the points

• Check the slope again

• Find another point

In the equation y = 2/3x + 1, what is the slope?

• 2

• 1

• 3

• 2/3

What is a common mistake when using the slope-intercept form?

• Ignoring the slope

• Starting from the origin instead of the y-intercept

• Using the wrong formula

• Plotting the x-intercept first

In the equation y = -1/3x + 5, what is the y-intercept?

• 0

• -1/3

• 1/3

• 5

For the equation y = 2x - 3, what is the slope?

• -3

• 3

• 2

• 1/2

How do you adjust the slope 2 to use it in rise over run form?

• 2/1

• 1/2

• 2/3

• 3/2
