Respuesta :

direct variation mean x =ky so y = x/k

(2,14) mean y = kx so 14 = k*2 so 14 = 7*2 so 14 = 14 
(4,28) mean y = kx so 28 = k*4 so 28 = 7*4 so 28 = 28

from these result that the 3rd choice is right sure 


The correct answer is option c. y = 7x is the equation that represents the function.

What is an equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

  • A direct variation function contains the points (2, 14) and (4, 28).

The equation will be given as:-

y = 7x  at (2, 14)

14  =  2  x  7  = 14

y = 7x  at (4, 28)

28  =  7  x  4  =  28

So the equation y  =  7x is satisfying both the points therefore correct answer is option c. y = 7x is the equation that represents the function.
