Question

This graph shows a proportional relationship.

Answer 1

Answer:

• k = 12

Step-by-step explanation:

One pair of coordinates is sufficient to work out the constant of proportionality.

Equation in general form:

• y = kx

and

• Point (3, 36)

Substitute x- and y- coordinates into equation and find the value of k:

• 36 = k*3
• k = 36/3
• k = 12
