Answer 1

The answer should be -1/2.

Answer 2

As we move from left to right, the graph goes thru (0,5) and (2.5,0).
                                                                                                         -5
Thus, the "run" is 2.5 and the "rise" is -5.  The slope is then m  = ------
                                                                                                         2.5

or m = -2 (answer).
