Select the equation that has a constant of proportionality:A. 16 + x = yB. 16x =yC. 16x -11 = yD. 16x + 15 = y

The equation that has a constant of proportionality is 16x = y ⇒ answer BStep-by-step explanation:A constant of proportionality is the constant value of the ratio of two proportional quantitiesIf x and y are proportional, then usually written y = kx k is the factor of proportionalityk = [tex]\frac{y}{x}[/tex] ⇒ constant ratioThe 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 = kxThe equation that has a constant of proportionality is 16x = yLearn more:You can learn more about  proportionality in brainly.com/question/10708697#LearnwithBrainly
