Equations for proportional relationships

ANSWER. Only A Only B Both A and B Neither

The equation that represents a proportional relationship, or a line, is y = k x, where k is the constant of proportionality. Use k = y x from either a table or a graph to find k and create the equation. Proportional relationships can be represented by tables, graphs and equations.Improve your math knowledge with free questions in "Proportional relationships: complete a table and make a graph" and thousands of other math skills.

Graphing proportional relationships Get 3 of 4 questions to level up! Lesson 4 ... A ratio is a comparison of two quantities. A proportion is an equality of two ratios. To write a ratio: Determine whether the ratio is part to part or part to whole. Calculate the parts and the whole if needed. Plug values into the ratio. Simplify the ratio if needed. 3 : 5 and 6 : 10 are equivalent ratios. That means these ratios are proportional. We can represent this proportionality using fractions: \(\frac{3}{5} = \frac{6}{10}\) This conveys that the two ratios are proportional. To verify this proportionality, we can perform arithmetic operations on the left-hand side of the equation.
