A; choose two points on the graph to be [tex]x_{1}[/tex], [tex]x_{2}[/tex], [tex]y_{1}[/tex], and [tex]y_{2}[/tex] in the slope formula, [tex]m= \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex] (the vertical axis is the [tex]y[/tex] axis, and the horizontal one is the [tex]x[/tex] axis).
[tex]m= \frac{30-6}{5-1} [/tex]
[tex]m= \frac{24}{4} [/tex]
[tex]m= \frac{6}{1} [/tex]
The slope is [tex] \frac{6}{1} [/tex], [tex]6[/tex] being the amount in savings and [tex]1[/tex] being the number of weeks.
