Question

Which is the slope of the like represented by the equation 2x+3y=-12

Answer 1

`\text{The slope-intercept form:}\ y=mx+b\\m-slope,\ b-y-intercept\\\\2x+3y=-12\qquad|\text{subtract 2x from both sides}\\\\3y=-2x-12\qquad|\text{divide both sides by 3}\\\\y=-(2)/(3)x-4\\\\Answer:\ \boxed{m=-(2)/(3)}`

Answer 2

slope = -
`(2)/(3)`

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 3y = - 12 into this form

subtract 2x from both sides

3y = - 2x - 12 ( divide all terms by 3 )

y = -
`(2)/(3)` x - 4 ← in slope- intercept form

with slope m = -
`(2)/(3)`
