Final answer:
To find Brenda's hourly rate for her cell phone bill, we need the slope of her billing pattern's linear equation. Without the graph or specific equation details, we can't calculate her rate accurately. The linear functions mentioned have different initial values and different rates of change.
Step-by-step explanation:
To understand Brenda's hourly rate for her cell phone bill, we need to look at the slope of the linear function that represents her cell phone billing pattern. A linear function is generally written in the form y = mx + b, where m represents the slope, i.e., the rate of change, and b represents the y-intercept, i.e., the initial value.
Given the information that the linear functions have different initial values and different rates of change, we can conclude that Brenda's plan does not share the same fixed monthly cost (initial value) or the same hourly rate (rate of change) as another given plan.
However, to determine Brenda's exact hourly rate, we would need specific information about the line that represents her billing pattern, such as two points on the graph or the slope and y-intercept of her linear equation.
Without the graph or these pieces of information, we cannot calculate her hourly rate with certainty.
Your complete question is: The linear function graphed below represents Brenda's monthly cell phone bill based on the number of hours she uses. What is her hourly rate?
1) The initial values of the two functions are different, and the rates of change of the two functions are also different.
2) The initial values of the two functions are different, and the rates of change of the two functions are the same.
3) The initial values of the two functions are the same, and the rates of change of the two functions are different.
4) The initial values of the two functions are the same, and the rates of change of the two functions are also the same.
