JournalWriting Prompts o Give your own example of a direct variation and explain why your example meets the criteria.

. The linear equation is given by y kx. The distance the car travels as time progresses is an example of direct variation. Now we have the variation equation as follows.

O What does a graph of the equation for a direct variation look like. Where k is a constant of proportionality and x 0. There is a constant rate of change.

The graph of a direct variation proportional relationship is a straight line that passes through the origin. Variables in direct variation can be modeled by the equations. The graph of two variables in direct variation is simply a straight line.

The equation is ykx where k is a constant which is apparent when we write the equation as yxk. Well a good example is speed and distance. As this is a direct relationship.

So the constant of proportionality becomes. Direct Variation Graph The graph of eqykx eq is a linear relationship with slope equal to the value of eqk eq the variation constant and a y-intercept located at the. On a direct variation graph the graph will always pass through 1 k where k is the.

A graph shows direct variation if it goes through the origin 00. In this lesson students will learn what direct variations are. They will know what the structure of a Direct Variation equation table graph and context lo.

The graph regarding the direct variation formula is considered to be in a straight line. Y 625 62. The graph of two quantities in a direct variation will result in a straight line.

Thus direct variation represents a linear equation in two variables. The equation has the form y kx and it has only two. Direct variation is a linear relationship between two variables x and y where the ratio y x is always equal to a constant value k.

The bigger your speed the farther youll go over a given time period. A car travels at a constant rate of 50 miles per hour. So as one variable goes up the other goes up too and thats the idea of.
