Yes , you obviously have to add that. Thats the part of your either Y or X axis value so you cannot ignore that.

I guess the only way that could have happened is the significant figures used in the calculation of the gradient got cancelled of each other therefore not making a difference. But it is necessary to add them. You can check M/J - 2010 - Variant 1 - Q2. That one has a graph with a 10^-3 axis.
