Using Absolute Value to Find Distances Between Points on a Coordinate Plane

This lesson teaches how to use absolute value to find distances between points on a coordinate plane. It begins with a review of absolute value, explaining it as the distance from zero on a number line. The lesson addresses common mistakes in plotting points, such as incorrect axis movement and returning to the origin. It demonstrates plotting points and calculating distances using absolute value, focusing on points with shared x or y values. The lesson concludes by reinforcing the concept of using absolute value to determine distances between points with shared coordinates.

What is the absolute value of -3?

• 6

• 0

• 3

• -3

When plotting the point (6, 4), which axis should you move along first?

• z-axis

• x-axis

• y-axis

• Return to origin

What is a common mistake when plotting the point (6, 4)?

• Moving along the x-axis first

• Returning to the origin after plotting x

• Plotting on the z-axis

• Ignoring the y value

How do you find the distance between two points with the same x value?

• Subtract the y values

• Add the x values

• Add the y values

• Subtract the x values

What is the distance between the points (0, 4) and (6, 4)?

• 4 units

• 6 units

• 2 units

• 10 units
