Equations for proportional relationships.

Proportion says that two ratios (or fractions) are equal. Example: We see that 1-out-of-3 is equal to 2-out-of-6. The ratios are the same, so they are in proportion. Example: Rope. A rope's length and weight are in proportion. When 20m of rope weighs 1kg , then: 40m of that rope weighs 2kg. 200m of that rope weighs 10kg.Jul 30, 2014 ...

If you can see that there is a single value that we always multiply one quantity by to get the other quantity, it is definitely a proportional relationship. After establishing that it is a proportional relationship, setting up an equation is often the most efficient way to solve problems related to the situation.The equation of a proportional relationship is of the form \(y=kx\), where \(k\) is a positive number, and the graph is a line through \((0,0)\). What would the graph look like if \(k\) were a negative number?Improve your math knowledge with free questions in "Proportional relationships" and thousands of other math skills.Please help keep Khan Academy free, for anyone, anywhere forever.
