what is the intial value and rate of change in this graph. please explain step by step!!!!!

The initial value of the graph is where [tex]x = 0[/tex]. Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
[tex]\dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
Let's use two points from the chart to find the slope:
[tex]m = \dfrac{30 - 21}{2 - 1} = 9[/tex]
In this case, the rate of change of the graph is 9.
