1. Which of the following questions has a constant of
garik1379 [7]

Answer:

In B)  y = x/7 , the constant of proportionality is 7.

Step-by-step explanation:

Two quantities X and Y are said to be in proportion if and only if

X = kY   or, \frac{X}{Y}  = k,

where k =  Proportionality Constant.

Here, 7 is the constant of proportionality. Then,

A .   y = 14x

here, \frac{y}{x}  = 14  ≠ 7

B .   y = x/7

here, \frac{x}{y}  = 7  = constant of proportionality .

C.   y = x

here, \frac{y}{x}  = 1  ≠ 7
