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
