metal and fan Sue earns $6 an hour walking her neighbor's dog. Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points) Part B: List three ordered pairs to show the values of the two variables. (3 points) Part C: Write an equation to represent the relationship between the two variables

I'll get right on it.

OpenStudy (scoobydo):

thanks

Let's work on Part A. We know that an independent variable is one that does not change throughout the problem. In this case, it would be the number of hours you work. The dependent variable is the one that changes in response to the independent variable, so in this case it would be the money that is the dependent variable. Do you understand this? Yes/No

OpenStudy (scoobydo):

yes now part b PLEASE

Okay... We can think of an ordered pair as a line on a coordinate grid. When the x value (independent value) changes, the slope of the line will change the y value (dependent variable). So, let's do some simple multiplication. We get $6 for every hour, so we can write the statement as y = x times 6. So, if we worked for 1 hour we would get $6. 2 hours is $12. 3 hours is $18. Are you understanding this?

I pretty much answered both questions btw.
