Answer:
the answer to the question is y=x+2.
That would be 8. 1/4 goes into 1 4 times so it goes into 2 8 times.
The lengths of sides of a triangle have to satisfy the triangle inequality, which states that the sum of the two shorter sides must exceed the length of the third side.
Here 9+8=17 (not greater), so these segments do not form a triangle.
