Answer:

y = 1.5x + 5

Step-by-step explanation:

The slope(m) is 1.5

The line passes through (0,5)

Taking another point (x,y) on the line;

Slope(m) = change in y ÷ change in x

1.5 \frac{y - 5}{x - 0}

Cross multiplying gives;

y = 1.5x + 5

So the range of profit or p is:

p=[-500, +oo)

Profit increases as the number of knives sold increases.  $200 more profit is gained by each sale of a knife.

4000=200k-500

4500=200k

k=22.5

Since k is for knives sold, it must be an integer value, so a $4000 profit is not possible.  At 22, p=3900 and at 23, p=4100
