we will put ur equation in y = mx + b form, and the slope will be in the m position.
14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7
y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.

y=mx+b
m=slope
or othe way
ax+by=c
slope=-a/b
14x+7y=-9
slope=-14/7=-2
slope=-2
