Question

Select the equation that has a constant of proportionality:

Answer 1

The equation that has a constant of proportionality is 16x = y ⇒ answer B

Step-by-step explanation:

A constant of proportionality is the constant value of the ratio of two proportional quantities

• If x and y are proportional, then usually written y = kx
• k is the factor of proportionality
• k = $\frac{y}{x}$ ⇒ constant ratio
• The graph which represent the equation of proportionality must pass through the origin point (0 , 0)

∵ The equation is represent proportionality

∴ The equation must be in the form y = kx

∵ Answer A is ⇒ 16 + x = y

∴ Answer A is not in the form of y = kx

∵ Answer B is ⇒ 16x = y

∴ Answer B in the form of y = kx, where k = 16

∴ Answer B has a constant of proportionality

∵ Answer C is ⇒ 16x - 11 = y

∴ Answer C is not in the form of y = kx

∵ Answer D is ⇒ 16x + 15 = y

∴ Answer D is not in the form of y = kx

The equation that has a constant of proportionality is 16x = y
