What is the slope of the line represented by the equation 2x+3y= –12 ? –32 –23 23 32
mr_godi [17]

Answer:

Option 2 - m=-\frac{2}{3} is the slope of the equation.

Step-by-step explanation:

Given : Equation 2x+3y=-12

To find : What is the slope of the line represented by the equation ?

Solution :

The slope form of line is y=mx+c

Equation 2x+3y=-12

Take 2x to another side,

3y=-12-2x

Divide 3 both side,

y=\frac{-12-2x}{3}

y=\frac{-2}{3}x-4

On comparing with general equation,

m=-\frac{2}{3} is the slope of the equation.

Therefore, option 2 is correct.
