Answer:

A=6 and B=4.5

Step-by-step explanation:

You are given table

\begin{array}{cccccc}x&2&4&[A]&7&9\\y&1&2&3&3.5&[B]\end{array}

If the paired values are in a proportional relationship, then

\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{[A]}{3}=\dfrac{7}{3.5}=\dfrac{9}{[B]}.

Note that

\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{7}{3.5}=2,

then

\dfrac{[A]}{3}=2\Rightarrow [A]=6,\\ \\\dfrac{9}{[B]}=2\Rightarrow [B]=\dfrac{9}{2}=4.5.
