Question

What is the slope of the line 3x – 9y = 4? –3 –negative StartFraction one-third EndFraction StartFraction one-third EndFraction 3

Answer 1

⅓

Explanation:

3x - 9y = 4

9y = 3x - 4

y = (3/9)x - (4/9)

y = (1/3)x - 4/9

Answer 2

1/3

Explanation:

3x – 9y = 4

We need to solve for y

Subtract 3x from each side

3x – 9y-3x = 4-3x

-9y = -3x+4

Divide each side by -9

-9y/-9 = -3x/-9 +4/-9

y = 1/3 x -4/9

This is in the form y = mx+b where m is the slope and b is the y intercept

y =1/3x -4/9

The slope is 1/3
