Pls help I really need it

First, lets make this right triangle. One leg will be from (0,10) to (0,2) and the other will be from (0,2) to (6,2). To find how long the legs are, just subtract the two points from each other. This leaves us with two lengths, 8 and 6. Now we are ready to use the Pythagorean Theorem, and solve for C.

A² + B² = C²

8² + 6² = C²

64 + 36 = C²

100 = C²

C² = 100

= 10

C = 10

Using the Pythagorean Theorem, we know know that the length of line segment AB is 10.

Hope this helps :)

The answer is C. I took the test and got it right
