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. 
First of all: subtract 3 from 3x then from 2y then divide
Area=basexhigh so, Area= 6x3 , so answer will be 18
