Answer 1

Given:

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.

Slope:

The slope of the equation can be determined using the formula,

`m=(y_2-y_1)/(x_2-x_1)`

Substituting the coordinates, we get;

`m=(100-20)/(10-0)`

`m=(80)/(10)`

`m=8`

Thus, the slope of the linear equation is $8.

Hence, $8 is put away each week.
