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

answer: it's d

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
