[A]: " (0, 0) " ; is correct;

Since, when "x = 0" and y = 0 :

"0 > - 4 " ; which is correct.

[B]: "(2, 1)" is incorrect, since:

when "x = 2" and "y = 1" ;

" 1 > 6" ; is incorrect.

[C]: "(-2, -1)" ; is correct;

Since, when "x = -2" and y = -1" ; then:

"-2 > -6 ; which is correct.

Answer:

For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.

Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.

A sketch of this situation can be seen below.
