Question

The graph shows the earnings of two employees working at the same company both earn money at constant rates please help me figure out which table the unit rate that matches each graph thank you so much

Answer 1

On the first graph, when x moves 1 unit, that is, from x = 2 to x = 3, the change in y is

`\begin{gathered} \Delta y=y_2-y_1 \\ =87-58 \\ =29 \end{gathered}`

Unit rate of the first graph is $29 per hour.

On the second graph, when x moves 1 unit, that is, from x = 0 to x = 1, the change in y is

`\begin{gathered} \Delta y=y_2-y_1 \\ =22-0 \\ =22 \end{gathered}`

Unit rate of the second graph is $22 per hour.
