Sagot :

Answer:

  • 2/5

Step-by-step explanation:

Proportional relationship is:

  • y = kx, where k is the constant of proportionality

We have a point (5, 2). it means x = 5, y = 2

Substitute x and y and find k:

  • 2 = k*5
  • k = 2/5

Answer:

2/5

Step-by-step explanation:

x = 5

y = 2

y = cx

2 = c × 5

c = 2/5

So, the constant of proportionality of the relationship is 2/5
