Question

The graph of a proportional relationship passes through the point (5, 2) . What is the constant of proportionality of the relationship?

Answer 1

2/5

Explanation:

x = 5

y = 2

y = cx

2 = c × 5

c = 2/5

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

Answer 2

• 2/5

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
