To find the equation that represents Aunt Andrea's decorating plans, I started by looking at the table that showed how much she decorated based on the number of days. I noticed that for each day, she added the same amount of decorations.
I counted how many decorations she added each day and figured out that it goes up by a certain number each time. This helped me find the slope of the line. I also looked at the starting point (the y-intercept) when no days had passed, which was the number of decorations she had at the beginning.
Then, I wrote an equation in the form of \(y = mx + b\), where \(m\) is the amount added each day and \(b\) is the starting number of decorations. This equation now shows how many decorations Aunt Andrea has based on the days she spends decorating!
