Question

Suppose you are saving money for a new cell phone. At week 0 you have $20 and at week 10 you have $100. If y represents the amount of money you have saved and x represents
one-eighth; $8 is put away each week.
Image with alt text: one-eighth ; $8 is put away each week.

10; $10 is put away each week.
10; $10 is put away each week.

8; $8 is put away each week.
8; $8 is put away each week.

one-tenth; $10 is put away each week. the number of weeks, find and interpret the slope of the linear equation

Answer 1

To find and interpret the slope of the linear equation, we need to determine the change in y (amount of money saved) for each unit change in x (number of weeks).

In this case, since $8 is put away each week, the slope of the linear equation is 8.

So, for every additional week, the amount of money saved increases by $8.

Therefore, the slope of the linear equation represents the rate at which the money is being saved per week.
