the graph of the function models simple interest growth. what is the annual increase in the total account…

Explanation:

Step1: Recall slope - formula for linear growth

The graph represents a linear function for simple - interest growth. The annual increase is the slope of the line. The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.

Step2: Select two points

Let's take the points $(0,110)$ and $(1,115.5)$. Here, $x_1 = 0$, $y_1=110$, $x_2 = 1$, and $y_2 = 115.5$.

Step3: Calculate the slope

Substitute the values into the slope formula: $m=\frac{115.5 - 110}{1-0}=\frac{5.5}{1}=5.5$.

Answer:

$5.50$
