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.
$18,617.75 is the answer
$87,525-$77,100=$10,425 (the amount over $77,100)
$10,425 x .28=$2,919 (the 28% taxed amount over $77,100)
$2,919+$15,698.75 (the already taxed amount in the chart)=$18,617.75
This answer would be false srry if im wrong but thats what i think
1 meter :12 cm
1 cubic meter = 1 x 1 x 1 : 12 x 12 x 12 = 1,728 cubic cm.
