Answer:
Here graph of an equation given.
The co-ordinates in the graph given are (0,0), (9,72), (18,144), (36,288), (45,360).
(0,0) point means, for x =0, y=0
(9,72) point means, for x =9, y=72
(18,144) means, for x =18, y=72
(36,288) means, for x = 36, y=288
(45,360) means, for x = 45, y =360.
We know that, , , , , ,
That means in each point, y value is 8 times the x value.
That means, we can write the equation as which also shows the proportional relationship of the graph.
So we have got the required answer.
The required equation is .
