Question

Mr. Bean borrowed three dollars to open a TV network. He lost two dollars each day.

Answer 1

Since Mr. Bean is losing $2 each day, he will have lost a total of 2*D dollars in D days.  He also started with $3 of debt ($-3) when D = 0
Therefore his total amount of money is starting amount - total losses or -3-2*D
so M = -2*D - 3

Answer 2

So loss of 2 per day
represent x for number of days
let y represent earnings (if negative,assume loss)
x=0 then y=-3
x=1, then y=-5
so  each day is -2 so
-2 times days or -2x
subsitute
y=-2x
if x=0 then y=-3
y=-2(0)+b
-3=0+b
b=-3

equation is
y=-2x-3

whoopes sorry
m=money
d=days then
m=-2d-3
