question

Find the distance between the points

(

)

and

(

)

units

solution

The distance between the points

(

)

and

(

)

is the length of the line segment that connects them.

Both points have an

-coordinate

of 8, so the line segment is vertical.

You can count to find the line segment's length. Start at

(

)

and count to

(

)

The line segment is 6 units long.

Another way to find the distance between

(

)

and

(

)

is to look at the distance from each point to the

-axis.

The difference in these distances is the length of the line segment that connects the points.

The

-coordinate

(

)

is 9, so this point is 9 units from the

-axis.

The

-coordinate

(

)

is 3, so this point is 3 units from the

-axis.

Subtract to find the length of the line segment.

–

The distance between

(

)

and

(

)

is 6 units.
