compare proportional relationships practice

Answer 1

1. In a proportional relationship, the two quantities change at a constant ratio. For example, if the first quantity doubles, the second quantity will also double.

2. Proportional relationships can be represented graphically as a straight line passing through the origin (0,0) on a coordinate plane.

3. In a proportional relationship, the two quantities maintain the same ratio no matter what values they take on. This means that as one quantity increases or decreases, the other quantity will change in proportion.

4. Proportional relationships can be written as equations in the form y = kx, where y and x are the two quantities involved and k is the constant of proportionality.

5. When comparing proportional relationships, it is important to look at the constant ratio between the two quantities, as this will determine if they are proportional or not.
