Math Problem Statement

Is this table proportional or non-proportional?

Solution

To determine whether the table is proportional or non-proportional, we need to check if the ratio between corresponding values of xx and yy is constant across all pairs.

From the table:

  • xy=82=4\frac{x}{y} = \frac{8}{2} = 4
  • xy=164=4\frac{x}{y} = \frac{16}{4} = 4
  • xy=246=4\frac{x}{y} = \frac{24}{6} = 4
  • xy=328=4\frac{x}{y} = \frac{32}{8} = 4

Since the ratio xy\frac{x}{y} is constant (always 4), this means the table is proportional.

Let me know if you need further details or have any questions!

Here are some follow-up questions:

  1. What is the ratio of xx to yy called?
  2. How would you identify a non-proportional relationship in a table?
  3. Can you write an equation for the proportional relationship from this table?
  4. How can you graph a proportional relationship?
  5. What are other real-life examples of proportional relationships?

Tip: For any proportional relationship, the graph will always be a straight line through the origin!
