Question

What is the slope of the line represented by the equation

2x + 3y = - 12?

a) -3/2

b) -2/3

c) 2/3

d) 3/2

Answer 1

make slope int form: y = mx + b
2x + 3y = -12
Subtract 2x from both side
3y = -2x - 12
Divide by 3
y = -2/3x - 4
y = mx + b, m = slope

Solution: -2/3

Answer 2

b) -2/3

Explanation:

2X + 3Y = - 12

3Y = -2X - 12

Y = - 2/3X - 6

SLOPE = - 2/3
