Question

Which is the unit rate, k, in the proportional relationship y = kx shown in the table?

Answer 1

Given a table that represents the relation between (x) and (y):

We will find the unit rate (k) in the proportional relationship y = kx shown in the table

From the given equation:

`\begin{gathered} y=kx \\ \\ k=(y)/(x) \end{gathered}`

Choose the data of one raw to find (k)

so, from the first raw:

When x = -2, y = -1/2

`k=(-(1)/(2))/(-2)=(1)/(2\cdot2)=(1)/(4)`

So, the answer will be k = 1/4
