Answer:
0.2
Step-by-step explanation:
The graph shows that y ∝ x and y = mx ....... (1)
{Where m is called the constant of proportionality in algebra and is called the slope of the straight line in coordinate geometry}
Now, it is given in the graph that the straight line passes through the point (5,1).
Therefore, equation (1) will be satisfied by the point.
Hence, 1 = 5m, ⇒ m = 0.2
So, the slope or the constant of proportionality of the graph is 0.2. (Answer)
