Answer:
A
Step-by-step explanation:
Proportional means the x and y values are BOTH increases or BOTH decreases by the same amount.
examining each table we can look from left to right of the table to see if the values of oranges and cups of juice respectively increase by one.
for A,
the oranges go from 3 to 4 to 5 all increasing by increments of 1
the cups of juice go from 1 to 2 to 3 also increasing by 1
so check!
to verify that A's the only correct answer we examine the other tables.
for B,
the oranges go from 3 to 6 to 9 all increasing by increments of 3
the cups of juice go from 1 to 2 to 3 all increase by increments of 1
the oranges are increasing more faster than the cups of juice by a factor of 3 so
NOT check
for C,
the oranges go from 3 to 3 to 3, increasing/decreasing by increments of 0 (not really increasing/decreasing at all)
the cups of juice go from 1 to 2 to 3 all increase by increments of 1
the oranges are staying the same as the cups of juice increases so
NOT check
for D,
the oranges go from 3 to 5 to 7 all increase by increments of 2
the cups of juice go from 1 to 2 to 3 all increase by increments of 1
the oranges are increasing faster than cups of juice by a factor of 2 so,
NOT CHECK!
