Answer:

y = 0.4x

Step-by-step explanation:

The graph shows that the relation is linear, so we can model this relation with a linear equation:

y = ax + b

To find the value of the parameters, we should get two points from the line and use their coordinates in the equation.

From point (0,0), we have:

0 = a*0 + b

b = 0

From point (2,5), we have:

2 = 5a + b

a = 2/5 = 0.4

So the equation we want is:

y = 0.4x
