Can someone please help me on this question?

The table respent two linear functions the equation respented by the first tables is given

On a architect's drawing of a house, 1 inche representa 1.5

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
