Solve for y
3x-5y=9
-5y=-3x%2B9
y=%283%2F5%29x-1.8
parallel lines have the same slope.
y=%283%2F5%29x%2Bb
plug in the point
2=%283%2F5%29%28-5%29%2Bb
2=-3%2Bb
b=5
your new equation
y=%283%2F5%29x%2B5

Find an equation of the line
Containing the point (2,-5) and parallel to the line 3x-5y= 9
----------------
find the slope of the line
3x-5y= 9
y = (3/5)x + something
slope = 3/5
------------
Use y = mx + b and the point to find b
-5 = (3/5)*2 + b
b = -31/5
--> y = 3x/5 - 31/5
or 3x - 5y = 31
