Graphing a Line Using X&Y Intercepts

This video tutorial teaches how to graph a line using its X and Y intercepts. It explains the concepts of X and Y intercepts, common mistakes in plotting them, and provides examples to illustrate the correct method. The tutorial also includes a practical problem involving a skateboard ramp to demonstrate the application of these concepts in real-world scenarios.

What is the X intercept of a line?

• The midpoint of the line

• The slope of the line

• The point where the line crosses the Y axis

• The point where the line crosses the X axis

What is a common mistake when plotting intercepts?

• Not labeling the axes

• Plotting the intercepts at the origin

• Using the wrong scale

• Switching the X and Y intercepts

What is the correct way to plot the intercepts of a line?

• Place the Y intercept on the X axis and the X intercept on the Y axis

• Place the X intercept on the Y axis and the Y intercept on the X axis

• Place both intercepts on the origin

• Place the X intercept on the X axis and the Y intercept on the Y axis

How do you find the X intercept of the equation 3X + 8Y = 24?

• Set X to 0 and solve for Y

• Set Y to 0 and solve for X

• Set X to 1 and solve for Y

• Set both X and Y to 0

What is the Y intercept of the equation 3X + 8Y = 24?

• X = 0

• Y = 3

• X = 8

• Y = 0

In the skateboard ramp example, what is the vertical height of the ramp?

• 9 feet

• 6 feet

• 3 feet

• 12 feet

What is the horizontal length of the skateboard ramp?

• 6 feet

• 9 feet

• 12 feet

• 3 feet
