Question

What is constant of proportionality represented in the graph?

4/3
3/4
1/3
4/1

Answer 1

In a proportional relationship (line through the origin), the proportionality constant is y/x for any chosen point (x,y) on the graph with x nonzero.

Answer 2

The constant of proportionality is 3/4

The constant of proportionality can be obtained using the relation ;

• y = kx ; k = proportionality Constant

Using the pair of points from the graph; (4, 3)

Now we have

3 = 4k

solve for k

k = 3/4

Hence, The constant of proportionality is 3/4
