Jason loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Jason knows the exercises wil
l help him play better though, so he tries to motivate himself using his favorite treat — chocolate chip cookies. Jason gives himself 5 cookies for every hour he practices.
There is a proportional relationship between the amount of time (in hours) that Jason practices the piano, x, and how many cookies he gives himself, y.
Graph this relationship. Select two points to draw a line.
What is the slope of the line?

Answer:
Step-by-step explanation:
Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².
Hope this helped!
