#1**+2 **

First one

[ x^2 + 3x - 28 ] / [ x + 7] factor the numerator

[ (x + 7) (x - 4) ] / ( x + 7) =

x - 4

The "hole" will occur where x + 7 = 0 ⇒ x = - 7

So plugging in x = -7 into x - 4, we get -7 - 4 = -11

So....the coordinates are ( -7, - 11)

Second one.....the third graph is the correct one
