a. Complete the table.
b. Use the values from the table to complete the graph by filling in the empty boxes. Then use the graph to ask yourself these questions:
· What does the horizontal axis represent? What variable did you use to identify it?
· What does the vertical axis represent? What variable did you use to identify it?
· How are the ordered pairs in the graph related to the values in the table?
· How are the horizontal and vertical distances shown on the graph related to the values in the table?
c. How can you write an equation that shows how the two variables are related?
d. What does the line in the graph represent?
a. How is the equation from 1c different from the equations earlier in this chapter?
b. One of the variables in this equation dependson the other variable. Determine which variable is which by answering the following questions:
b. One of the variables in this equation dependson the other variable. Determine which variable is which by answering the following questions:
b. One of the variables in this equation depends on the other variable. Determine which variable is which by answering the following questions:
· Does the amount of money you earn depend on the number of hours you work?
· Does the amount of money you earn depend on the number of hours you work?
How do you think you can use these types of variables in real life?
a. Write the formula for the perimeter of a square. Tell what each variable represents.
b. Describe how the perimeter of a square changes as its side length increases by 1 unit. Use a table and a graph to support your answer.
