If the slopes of two lines are unequal, they will cross somewhere, so the distance between them depends on x, and isn't really defined.
If the slopes are equal, they are parallel, so they don't cross. So two lines are far apart if they have the same slope and a large difference in their x or y intercepts.
It depends on what kind of line you are dealing with.If you have the lines on paper...If they do not intersect, they are parallel.If they do, measure the angle. If it is 90° then they are perpendicular.If you have the equations of the lines. If the slopes are the same, but they have a different y-intercept, they are parallel.if the slopes are inverse reciprocals of each other (i.e. 2 and -.5) then they are perpendicular.■

lines that are beside each other and never meet
Perpendicular and parallel lines are two examples.
Parallel lines
If the "contour interval" ... the elevation difference between lines ... is the same everywhere on the map, then the lines will be closer rogether on steep ground, and farther apart on flatter ground.
Parallel lines-lines in the same plane with the same slope.
The slopes of perpendicular lines are reciprocals of each other. For example. if one line had an equation like y= 2x+4 then the perpendicular's slope would be y=x/2+4 -- they are reciprocals of each other.

Relief
Contour lines that are far apart indicate a gentle slope. Because contour lines connect points with the same elevation, wide spacing indicates that the elevation is not changing drastically.
Italic printing slopes to the right, with the letters slanting to the right at an angle. Italic fonts are often used to emphasize text or for decorative purposes in design and typography.
These are either VERY old mountains formed by the crust compressing or mountains formed by the crust slowly pulling apart over time.

Elements are identified from bright light line spectra by analyzing the unique pattern of emission lines produced when the element is heated. Each element emits a specific set of wavelengths of light, resulting in a distinct spectral fingerprint that can be compared to known spectra to determine the element present. This technique is known as spectroscopy and is commonly used in chemistry and astronomy.
