Both linear and proportional because as x increases y decreases at the same rate
The predicted number of plants with aphids is 109.
<h3>What is the predicted number of plants with aphids?</h3>
The predicted number of plants with aphids is the ratio of the random plants with aphids to total number of random plants selected multiplied by the number of plants in the nursery.
Predicted number = (7/50) x 780 = 109.

ANSWER
The constant of proportionality is 24.
EXPLANATION
If the volume of a box (V) varies directly with it's length (l), then we can write the mathematical statement,
We introduce the constant of proportionality k, and write the equation,
When V=288, l=12.
We substitute these values to obtain;
Divide both sides by 12,
1) B
This is because the x value = quarts and the y value = pints, there are 3 quarts and 6 pints.
2) A
Its going up 2 every time in the y axis, rise over run= 2 over 1
3) C
They are both at 0
