I'm taking the same final test.
The answer is y= 1/4x - 5
How? Well in this case we are using the formula y= mx + b
Substituting it with the given point (8, -3) and the slope 1/4
it'll look like -3 = 1/4 (8) + b
Next we solve.
-3 = 1/4 (8) + b
-3 = 8/4 + b
-3 = 2 + b
-2 -3 = b
-5 = b
so we now we know that b = -5.
All we have to do is substitute that into the equation to get our final answer (this time, without the point 8,-3).
Our answer in the end is y = 1/4x -5

Answer:
$108
Step-by-step explanation:
The computation of the total profit is shown below:
Given that
1 box = $12
18 boxes = 12×18 = $216
So
Total = 18×65 = 1170 pens
Now Cost price, Cp = $216
Also,
3 = $1
So,
= 378 ÷ 3
= $126
Now
= 1170-378
= 792 pens remaining
4 = $1
So,
792
= 792 ÷ 4
= $198
Now
Total selling price, sp = 126+198 = $324
So finally
Profit = Sp - Cp
= $324 - $216
= $108
7/8 x = 21
7x = 21×8
7x = 168
x = 24
