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=(y)/(x)=(2.25)/(-3)=(0.75)/(-1)=(-1.5)/(2)=(-3.75)/(5)=-(3)/(4)`
