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
<u>k=3</u>
Now, putting the value of k in equation (i), we get
The equation of the graph is y=3x.
<h3>★ <u>B</u><u>. y=3x</u> is the right answer.</h3>
