Simple...
you have: 8x-6y=1
You're trying to find m-->>using y=mx+b to re-write the line....
8x-6y=1
8x-6y=1
-8x -8x
-6y=-8x+1

y=
Your slope m=
Thus, your answer.
$4.7 × 915 = 4300.5
$4300.5 + 79.15 = 4379.65
15% of 4379.65 = 656.9475
4379.65 + 656.9745 = 5036.6245
Mrs. Jones' Bill was $5036.63
(Rounded to the nearest 1/10)
Obtaining thevslope you get 6/5. so
9=-24/5 +n
=
y=6/5x + 21/5
60% = 0.6
12 / 0.6 = 20
answer 12 is 60% of 20
The probability of getting at most 2 tails is 7/8
