Solution to QOTD 5/7/2020

To find the solutions to this, we need to look at the original table of values that is given: for each input (x), what is the relationship to the output (y)?

The table shows that for every hour worked, Kelli earns $15.00. So, the more hours she works, the more money she will make. Therefore, the function is increasing. Because the rate that Kelli is paid is a constant, the function is linear. And if Kelli works zero hours, she will make zero dollars, so the y-intercept will be (0,0).
