Hello, I hope you are having a splendid day. :)
The slope of this line is -5/4.
This equation is written in slope-intercept form, which looks like this:
y=mx+b
Where
m is the slope and b is the y-intercept.
So the slope is the number before x (in y=mx+b form).
The number before x is -5/4.
Therefore, -5/4 is the slope. Hope it helps. Ask me if you have any queries.
