What is the slope of the line?<br> 8x-6y=1<br><br> A:3/4<br> B:1/6<br> C:4/3<br> D:1/8
Vanyuwa [196]
Simple...

you have: 8x-6y=1

To find m (slope) re-write in y=mx+b form

8x-6y=1

8x-6y=1
-8x     -8x

-6y=-8x+1

Now simply divide by -6--->>

\frac{-6y}{-6} = \frac{-8x+1}{-6}

y= \frac{4}{3} x- \frac{1}{6}

m=\frac{4}{3}x

Thus, your answer.

Paraphin [41]

<em>In base four, each digit in a number represents the number of copies of that power of four. That is, the first digit tells you how many ones you have; the second tells you how many fours you have; the third tells you how many sixteens (that is, how many four-times-fours) you have; the fourth tells you how many sixty-fours (that is, how many four-times-four-times-fours) you have; and so on. </em>
