<u>Given</u>:
Let x represents the number of weeks.
Let y represents the amount of money.
Given that you are saving money for a new cell phone.
At week 0 you have saved $20 and at week 10 you have $100.
Writing this as coordinates, we get;
(0,20) and (10,100)
We need to determine the slope of the linear equation.
<u>Slope</u>:
The slope of the equation can be determined using the formula,
Substituting the coordinates, we get;
Thus, the slope of the linear equation is $8.
Hence, $8 is put away each week.
If n=5 then 2*5=10, 10+3=13.
