8!in is the initial value at 0 days which represents b=8
The rate of change is 3in per day, this rate is the slope m = 3
Now substitute
y = 3x + 8
Answer:1 r3
Step-by-step explanation:8 Divided by five
Step-by-step explanation:
First you must simplify the equation:
subtract 1 from both sides:
than divide both sides by -3, which switches the inequality sign:
This inequality means that all values of x greater than -2 work for the equation. because it is not 
, -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.
