Question

What is the slope-intercept form of the linear equation: −3x − 2y = 30

A.2y= 3x+30


B.y= (-2/3)x- 15


C.y= (3/2)x +30


D.y= (-3/2)x-15

Answer 1

Answer: D.
`y = (-3x)/(2) - 15`

Explanation:

-3x - 2y = 30

Slope intercept form is y = mx + b

just solve for y

1. Add -3x to both sides:

-2y = 3x + 30

2. divide both sides by -2

`(-2y)/(-2) = (3x + 30)/(-2)`

3. simplify

`y = (-3x)/(2) - 15`
