Answer:

Step-by-step explanation:
use y = mx + b
slope(m) =
y-intercept(b) = 3
so,

12.....because there are 4 quarters in $1
100-21=79
2859(0.79)^3=1409.598
worth $1409.60
(X,Y) 0=X and 0=Y if you plug in 0 for X and 0 for Y in Y=8X it will be 0=8(0). 8 times 0 is 0 which is the equation
Step-by-step explanation:
