-x=2y%2B5
First, put the given equation into y=mx+b form. Then you can just read the slope (m) off of the equation:
2y%2B5=-x
Add -5 to both sides of the equation:
2y=-x-5
Divide each side of the equation by 2:
y=-1x%2F2-5%2F2
Now, you can just read off the slope from the equation as the coefficient of x:
highlight%28m=-1%2F2%29

Good Luck,
