If at least $1 of profit is "profit", then 140x-2000=1
140x=2001
x=14.293
but need a whole value for x.
14 computers is not enough for "profit".
ANSWER: 15 computers.
------
Or the $1 part is not necessary.
140x=2000
x=200%2F14=100%2F7
x=14.286-------------Break-Even value, not a whole value result, so need 15 microcmputers.

The amount of profit would be $100.

For your info, equation has no slope.

In Math, a straight line may have a slope.

A linear function may have a slope (which is just a jargon).
