To find the slope, the best way is to 'convert' the equation in slope-intercept form,

The slope-intercept form is
y=mx%2Bb

where m=slope

Let's start!
y%2B4=%28-1%2F2%29%28x%2B3%29
2%28y%2B4%29=2%28%28-1%2F2%29%28x%2B3%29%29
2y%2B8=-%28x%2B3%29
2y%2B8=-x-3
2y%2B8-8=-x-3-8
2y%2B0=-x-11
2y=-x%2B-11
2y%2F2=%28-x-11%29%2F%282%29
y=-x%2F2-11%2F2

Here, m=-1%2F2. Therfore, the slope is -1%2F2
