Question

y = 9x or y = 8x
Which equation that show a proportional relationship between x and y

Answers

Both equations, \( y = 9x \) and \( y = 8x \), show a proportional relationship between \( x \) and \( y \).

In a proportional relationship, \( y \) is directly proportional to \( x \), which means that as \( x \) changes, \( y \) changes at a constant rate. This can be observed in both equations where:

- In \( y = 9x \), the constant of proportionality is 9.
- In \( y = 8x \), the constant of proportionality is 8.

Thus, both equations describe proportional relationships, with different constants of proportionality.
