Question

What is the value of k? The relationship between x and y shown in the table may be expressed as = kx, where k is the constant of proportionality. A) х у -3 2.25 -1 0.75 B 2 -1.5 5 3 -3.75 a -4/3 b -3/4 c 3/4 d 4/3

Answer 1

The relation is:

`y=kx`

so we solve for k is:

`k=(y)/(x)`

So the constant ofproporcionality is:

`\begin{gathered} k=(2.25)/(-3) \\ k=-0.75=-(3)/(4) \end{gathered}`

So is B
