What is the slope of the line 3x - 9y = 4?

1. - 3

2. - 1/3

3. 1/3

4. 3

3. 1/3

Step-by-step explanation:

Change the equation by isolating y

9y=3x-4

y=1/3x-4/9

this is slope intercept form.

y=mx+b

m=slope

∴slope=1/3

OR

your equation is in standard form Ax+By=C

slope=-A/B

-3/-9

1/3

∴slope is 1/3
