an horizontal line has the same slope in both coordinate systems, namely: slope=0

anonymous · Answer

so the slope of the horizontal line is 0?

michele_laino · Answer

yes! because the axis of your new coordinate system are parallel to the respective axis of the old coordinate system

anonymous · Answer

ok so then what is the slope of the vertical line?

michele_laino · Answer

the slope of a vertical line is infinity in both coordinate systems
