Khan Academy is a free online platform that offers math lessons and exercises for learners of all levels.Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x.

And when X is six, Y looks to be, 1 and 1/3 times X. So you don't have the same proportionality constant the entire time. So, we have zero proportional relationships depicted here. So I would pick zero there. Let's do one more example. Natalie is an expert archer. Proportional Relationships from Tables. When given a table that compares quantities, we can write ratios and then compare them to determine if they are proportional. Heather is creating towers of nickels and measuring the height, in millimeters, of the stacks. Her data is shown below. Number of Nickels. Height. Let's graph a proportional relationship from a table of values. The graph of a proportional relationship is a line, so we can graph from any 2 points in the table. The slope of the line represents the unit rate, so changes in x and y values determine the slope. Created by Sal Khan.The three main ways to represent a relationship in math are using a table, a graph, or an equation. In this article, we'll represent the same relationship with a table, graph, and equation to see how this works. Example relationship: A pizza company sells a small pizza for $ 6 . Each topping costs $ 2 .
