A function is created to model the situation where the day of the month, x, is the independent variable, and the height of low tide, T, is the dependent variable. Plot the two points that we know on a graph. Include a dotted line representing the monthly average low tide height, and appropriately label the axes. Note that x = 1 is July 1.

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !
