Question

The relationship between X and Y shown in the table may be expressed asVkx, where is the constant of proportionality310.75(B32

Answer 1

Given that y = kx, then k = y/x

Substituting with the values of the table, we get:

$k=\frac{y}{x}=\frac{2.25}{-3}=\frac{0.75}{-1}=\frac{-1.5}{2}=\frac{-3.75}{5}=-\frac{3}{4}$
