Note:

is the first point

. So this means that and .
Also,

is the second point

. So this means that and .

Start with the distance formula.

Plug in , , , and .

Subtract from to get .

Subtract from to get .

Square to get .

Square to get .

Add to to get .

Take the square root of to get .

So our answer is

So the distance between the two points is 2 units.

Note: If you plot the two points on a coordinate grid, you can easily count the number of spaces between the two points to be 6 units. However, this method only works if the two points have either the same x coordinate or the same y coordinate.
