Longitude and latitude.
Nodal Lines
-- Most of the imaginary lines on the surface are parallels of latitude, meridians of longitude, political boundaries, and shipping routes. -- The imaginary lines through the center of the globe are the axis and diameters.
Similarities:Both sets of lines may be printed on maps and globes in any desired color,with any desired thickness and at any desired interval, and can even notbe present at all.Difference:Longitude lines are semicircles, and are all the same length ... about 12,250 miles.Latitude lines are full circles, and their lengths range from zero to about 24,500 miles.
Many sets of data do not form into straight lines. If by "What if" you mean how to plot a line onto this graph. Then simply draw a curved line of best fit.
No, it can but it doesn't necessarily need a variable. I have no idea what the previous answer means. The earth spins on its axis. The spin axis provide the geographic north and south poles. On the other hand the earth's magnetism does not work like a bar magnet. Instead, the iron and cobalt core spins at a slightly faster rate than the rest of the earth. This sets up eddy electrical currents which creates magnetic fields. In the northern hemisphere, the magnetic fields join under Northern Canada.

there are 2 sets of parallel lines in a square
A square has four sets of parallel lines.
how many sets of parallel lines are in a triangle
2 sets of Parallel lines
There are no parallel lines in a triangle !
A square or rectangle has two sets of parallel lines. Stop signs technically have 4 short sets o parallel lines. Hexagon could have 3 sets, etc. All of which are polygons, though not all polygons have parallel lines.
You can't... A rectangle is defined by 2 sets of parallel lines, ans a parallelogram has 1+ sets of parallel lines
