Distance Between Points on a Coordinate Plane

This video tutorial explains how to calculate the distance between points on a coordinate plane when they share the same x or y value. It demonstrates the process using two examples: one where the points share the same y-value and another where they share the same x-value. The tutorial emphasizes that when points do not share the same x or y value, the distance cannot be calculated by simply counting spaces.

What is the first step in finding the distance between two points with the same y-coordinate?

• Draw a line between the points.

• Calculate the slope of the line.

• Count the spaces between their y-values.

• Count the spaces between their x-values.

How many units apart are points A (3, 5) and B (-6, 5) on the x-axis?

• 6 units

• 12 units

• 9 units

• 3 units

When two points share the same x-coordinate, what should you count to find the distance between them?

• The slope of the line connecting them.

• The total number of grid squares.

• The spaces between their y-values.

• The spaces between their x-values.

What is the distance between points X (-1, 2) and Y (-1, -4) on the y-axis?

• 4 units

• 7 units

• 5 units

• 6 units

Why can't you count spaces directly when points do not share the same x or y value?

• Because the points are too far apart.

• Because the distance is not a straight line.

• Because the points are on different axes.

• Because the points form a diagonal line.

What is a key takeaway when finding distances between points with shared coordinates?

• Use a calculator for accuracy.

• Calculate the midpoint first.

• Only count spaces along the shared coordinate.

• Always use a ruler.

What should you do if the ordered pairs do not share the same x or y value?

• Use the distance formula.

• Draw a line between the points.

• Count the spaces along the y-axis.

• Count the spaces along the x-axis.
