Explanation

Step 1

find the slope of the line, when you know 2 points of a line (P1 and P2) you can find the slope using:

[tex]\begin{gathered} \text{slope}=m=\frac{y_2-y_1}{x_2-x_1} \\ \text{where} \\ P1(x_1,y_1) \\ P2(x_2,y_2) \end{gathered}[/tex]

Let

P1(2,630)

P2(5,450)

replace,

[tex]\begin{gathered} \text{slope}=m=\frac{y_2-y_1}{x_2-x_1} \\ \text{slope}=m=\frac{450-630}{5-2} \\ \text{slope}=m=\frac{-180}{3} \\ \text{slope}=m=-60 \end{gathered}[/tex]

it means Latoya saves $60 each week, the neg
