F. Do the segments connecting the coordinates (-1,6), (4,2), and (7,6) form a right triangle? Show work that leads to your answer.

No, these segments do not form a right triangle.

Step-by-step explanation:

We need to calculate the distances between the points, taking 2 at a time:

From (-1, 6) to (4, 2), x increases by 5 and y decreases by 4.  The distance between the two points, by the Pythagorean Theorem, is d = √(5² + 4²), or √41.

From (-1, 6) to (7, 6) x increases by 8 but y stays the same:  6.  The distance between these two points is therefore 8.

Finally, from (4, 2) to (7, 6), x increases by 3 and y by 4, and so d = 5.

So now we have the 3 side lengths:  √41, 8 and 5.

Squaring them, we get 41, 64 and 25.  These do not satisfy the Pythagorean Theorem:  41 + 25 is not equal to 64.

No, these segments do not form a right triangle.

the answer is f(x)=2x-1
