Which of the sets of ordered pairs represents a function? (1 point) A = {(2, 7), (1, −5), (7, 2), (2, −9)}

B = {(5, 3), (−2, −9), (−3, 8), (9, 3)}

B = {(5, 3), (−2, −9), (−3, 8), (9, 3)}

Step-by-step explanation:

A function has no repeating inputs (x-values). One input is assigned to exactly one output.

In set 'A', the input of two is repeated.

A = {(2, 7), (1, −5), (7, 2), (2, −9)}

In set 'B', there are no repeating inputs.

Set 'B' is a function.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

its a straight line parallel to the time axis
