Triangle DEF and triangle PQR are similar and have the same orientation. The hypotenuse of triangle PQR is on the same line as the hypotenuse of triangle DEF and is one-third the length of DF. What is the equation of the line that the hypotenuse of triangle PQR lies on?

y =
x +

On the hypotenuse of triangle PQR, if coordinate P is at point (2, -4), then coordinate R is at point (
,
).
