What is the slope of a line parallel to the line y=-5x+13

-5/5 & and 5-5 I think that should be the correct answer unless I misunderstood

Alright, so there's a rule to parallel lines that says that whatever the slope is of one of the lines, all of the lines parallel to it are going to have the same slope. The slope you have here is - 5/1 or - 5, therefore, your slope for every other line parallel to it will be the same.
