Answer:

-5

Step-by-step explanation:

First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)

This would look like:

[tex]5x + y = 3\\y = -5x + 3[/tex]

This means the slope is -5.

Parallel lines always have the same slope, so the slope of the parallel line is also -5
