In a right triangle, the hypotenuse has endpoints XY, shown on the graph. On a coordinate plane, line X Y has points (negative 4
, 2), (negative 1, negative 3). If Z represents the third vertex in the triangle and is located in the second quadrant with integer coordinates, what is the length of YZ?
Note that the graph is shaped like a V. The left half of the graph is decreasing from -∞ up until 0 when it hits the origin and starts to increase. Put this into interval notation: (-∞,0).
