The constant of proportionality of the given graph is gotten as 4.
How to find the constant of proportionality?
The constant of proportionality here is simply the slope of the graph.
Now, we will take two points and use their coordinates to find the slope from the formula;
m = (y2 - y1)/(x2 - x1)
Let us pick 2 points which are;
(1, 4) and (2, 8). Thus;
m = (8 - 4)/(2 - 1)
m = 4/1
m = 4
Thus, the constant of proportionality of the graph is gotten as 4.
