Hey!
Let's simplifythe expression:
"Sum" is a term used to add. In this expression, you will be adding
"Quotient" is a term used to divide. In this case, you will be dividing x(a number) and 6
Quotient of a number and 6 = x ÷ 6
That gives you: 10 + (x ÷ 6)
The initial value of the graph is where . 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:
Let's use two points from the chart to find the slope:
In this case, the rate of change of the graph is 9.
