In a direct variation, y = 14 when x = 7. Write a direct variation equation that shows therelationship between x and y.Write your answer as an equation with y first, followed by an equals sign.Submit

Respuesta :

A direct variation (or proportional) relationship can be expressed as:

[tex]y=kx[/tex]

where k is the constant of proportionality or unit rate.

If we have a point where y=14 and x=7, we can calculate it as:

[tex]k=\frac{y}{x}=\frac{14}{7}=2[/tex]

We can then write the function as:

[tex]y=2x[/tex]

Answer: y=2x
