Question 122457
{{{-x=2y+5}}}
First, put the given equation into y=mx+b form. Then you can just read the slope (m) off of the equation:
{{{2y+5=-x}}}
Add -5 to both sides of the equation:
{{{2y=-x-5}}}
Divide each side of the equation by 2:
{{{y=-1x/2-5/2}}}
Now, you can just read off the slope from the equation as the coefficient of x:
{{{highlight(m=-1/2)}}}
