y is directly proportional to x.

 

 

 

 

 

 

 

1. Using the proportionality symbol, we can say that y∝x.

2. The formula which is related to the graph above can be written like so y=kx. ‘k’ is the constant of proportionality.


y is directly proportional to x squared.

y is directly proportional to x squared.

 

 

 

 

 

 

 

1. Using the proportionality symbol, we can say that y∝x².

2. The formula which is related to the graph above can be written like so y=kx². ‘k’ is the constant of proportionality.


y is directly proportional to x cubed.

y is directly proportional to x cubed.

 

 

 

 

 

 

 

1. Using the proportionality symbol, we can say that y∝x³.

2. The formula which is related to the graph above can be written like so y=kx³. ‘k’ is the constant of proportionality.


y is inversely proportional to x squared.

y is inversely proportional to x squared.

 

 

 

 

 

 

 

1. Using the proportionality symbol, we can say that y∝1/x².

2. The formula which is related to the graph above can be written like so y=k/x². ‘k’ is the constant of proportionality.

2. The formula which is related to the graph above can be written like so y=k/x. ‘k’ is the constant of proportionality.


y is directly proportional to the square root of x.

y is directly proportional to the square root of x.

 

 

 

 

 

 

 

1. Using the proportionality symbol, we can say that y∝√x.

2. The formula which is related to the graph above can be written like so y=k√x. ‘k’ is the constant of proportionality.
