What is the slope of the graph of 14x + 7y = - 9?

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
