When the pairs are put onto a coordinate grid you will notice Leslie is 10 units away from Jorge to the left. However the question is saying Jorge goes 10 units to the right. Which would be going further away from Leslie. Considering coordinate grids are made so in the top right it is 100% positive bottom right 50% positive its only positive on the x axis, which is the line through the middle. The bottom left is 100% negative. The top left is 50% negative as it is negative along the x axis. The x axis is plotted first and the y axis is plotted second.
Refer to the pdf I attached for some more information! Also the teal dot represents Leslie and the red one represents Jorge.
I hope this helps! If you need any more further help about this question please let me know.
