Answer 1

D

Explanation:

Given,

In the equation y = 2.5x + 4,where 'y' represents the kitten's weight in ounces and 'x' represents weeks after it's birth.

The point lies at (x,y) = (4,14)

here value of x is 4 and value of y is 14.

Substituting x=4 in the equation y = 2.5x + 4.

y = 2.5 * 4 + 4

y = 14.

Therefore,

The kitten weighed 14 ounces when it was four weeks old.
