Take a real-life situation and create an equation or inequality that could be used for analysis, prediction, or decision making. Then, draw a graph to depict the variables in your situation Use your graph and what you know about linear inequalities to discuss the significance of your findings

Question

This was my answer:
A good example for me of a straight line graph is to figure out your income for that specific pay period. I do this every week before I get paid. And now I am using it to my advantage to apply this activity to my math work. Every week before I get paid I calculate my hours times my rate of pay which would be a constant since I know I make $7.50 an hour. So then I can figure out the total pay I will receive. This may not work for everyone though; I have a set 40 hours a week. Some peoples hours worked may vary.

For the linear equation I would use my 4 year CD savings account as the example. I opened the account 1 year ago with a deposit of $1200. Since it is a CD account I cannot touch the money for 4 years until the required time is up (unless I close it before then, in which case I will be charged and early termination fee). The account has an interest rate of 0.09%, meaning so far I have made $108. Now I can use the known information to figure out how much money will be in the account after 4 years. The slope (which will be going up in a positive form) will represent how much money I have gained from interest each year.
