so after 2 minutes, 6 left and
5 minutes=0 left
so if x=2 then y6
if x=5 then y=0
x is obviously negative
y=-sometingx
find slope
(y1-y2)/(x1-x2)
(6-0)/(2-5)=6/-3=-2

so y=-3x+b
solve for b
if y=0 then x=5
0=-3(5)+b
0=-15+b
add 15 to both sides
15=b

the equation is y=-3x+15
y=mx+b
m=slope


A. equation is y=-3x+15

B. slope=-3
