In the coordinate plane, points (x, 3) and (5, y) are on line k. If line k passes through the origin and has slope 3/5, then x + y =	Choose one:
A) 9	B) 8	C) 7	D) 5	E) 6
Line k passes through the origin and has slope 3/5 means that its equation is y=3/5*x.   Thus: (x, 3)=(3, 5) and (5, y) = (3, 5) --&gt; x+y=3+5=
