Answer:
(x,y)=(0,0)
Step-by-step explanation:

2y=2x
multiply both sides -7x+3y=0
-x+y=0
eliminiate one vaiable
< P is a right angle.....a right angle is 90 degrees.
< P and < Q form a linear pair....a linear pair, when added, = 180 degrees
so if < P is 90.....and when added to < Q = 180...
90 + Q = 180
Q = 180 - 90
Q = 90 <== so < Q is also a right angle...measures 90 degrees
