A right triangle was graphed on a coordinate plane using the coordinates (2, 4), (6, 4), and (6, 10). What is the length of the base of the triangle?

The base of the triangle is the distance between the two points with the same y-coordinate: (2,4) and (6,4).

Using the distance formula:

√[(6-2)² + (4-4)²]

Simplifying:

√[4² + 0²]

= √16

= 4

Therefore, the length of the base of the triangle is 4 units.
