the parallel line will go through point (8,-9)

y = kx + n

9x - 2y = 5

2y = 9x -5

y = (9/2)x - 5/2 <<< the first line

Parallel lines have the same koeficient k.

k in your case = 9/2

now you insert the coordinates of the point through which the parallel line will go through.

-9 = (9/2) * 8 + n

- 9 = 36 + n

n = -45

y = (9/2)x -45
