You would keep the first fraction the same , turn the division sign into a multiplication sign , and flip the 2nd fraction upside down.
10/14 ÷ 7/16
10/14 x 16/7= 80/49 = 1 31/49

Parallel lines share the same slope, so the slope of the parallel line in this case must be
.
Point-slope form is
, where
is the slope and
is any known point on the line.
Plug in the values. 
Simplify and distribute. 
Subtract 1 from both sides. 
Answer:
Thank you, Also that is really cool
