Answer:
Choice A, C and E
Step-by-step explanation:
<em>Your table is poorly presented</em>
Given
x y

First, we calculate the constant of proportionality (k)

For (3,1.47)


For (5,2.45)


For (9,4.41)


From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
<u>Choice A</u>


--- <em>This is usable</em>
<em />
<u>Choice B</u>


--- <em>This is not usable</em>
<em />
<u>Choice C</u>


--- <em>This is usable</em>
<em />
<u>Choice D</u>


---- <em>This is not usable</em>
<em />
<u>Choice E</u>


--- <em>This is usable</em>
