Answer:

  • B. y = 3x

Step-by-step explanation:

Use one of the points on the graph to find the equation.

Let's take the point (1,3)

We know the proportional relationship is:

  • y = kx, where k is the coefficient of proportionality

Substitute the values from the point and solve for k:

  • 3 = 1*k
  • k = 3

The function is:

  • y = 3x

Correct choice is B

Answer:

The graph is in a proportional relationship (given)

Therefore, it is in the form y=kx where k is a constant.......(i)

Now in the graph we can locate that when the value of x is 1, the value of y will be 3

Putting the value of x and y in equation (i), we get

3=1×k

k=3

Now, putting the value of k in equation (i), we get

The equation of the graph is y=3x.

★ B. y=3x is the right answer.
