Question

What’s the slope and the balanced that’s decreases by $?

Answer 1

Given,

The line graph is passing through the points (3,835) and (8,560).

The slope of the line is calculated as:

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

Substituting the values of points then,

`\begin{gathered} m=(560-835)/(8-3) \\ m=(-275)/(5) \\ m=-55 \end{gathered}`

Hence, the slope of line is -55 and the balance decreased by $55 per month.
