There are no steps to show, you just have to know which part of the equation effects which part of the graph:
Eqn. 5 matches b (since there were absolutely no translations)
Eqn. 6 matches d (since there was a vertical translation of one upwards)
Eqn. 7 matches a (since there was a horizontal translation of one to the right)
Eqn. 8 matches c (since there was a reflection upon the y-axis and a vertical translation of two downwards)
