Khan Academy: Constant of Proportionality From Equations

Practice finding the constant of proportionality from tables with equations.

Practice finding the Constant of proportionality from tables.

Practice finding constant of proportionality from graphs.

In this exercise, students practice writing function rules from equations. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

In this lesson, you will learn how to identify the constant of proportionality from a labeled diagram by writing an equation of the form y=mx and solving for m. [3:56]

Try several practice two-step equation word problems. Answer correctly and move on; answer incorrectly and Khan Academy provides relevant tutorials.

Video explores how to compare a rate given in an equation to a rate shown on a graph. [1:24]

Video explores rates and proportional relationships using a gas mileage problem. [3:18]

This tutorial will highlight that what you do to one side, you have to do to the other in one-step multiplication equations. [2:23]

An introduction to basic algebraic equations of the form ax=b. Check to see if you have the right answer by substituting it for the variable. [11:06]
