It depends on the scale of the map. On a map of the world or a continent, the parallel lines will generally go horizontally across the map - East to West. For a large scale map, showing a small country or a local area, the vertical lines (North - South) will also be shown as parallel.

Construction, engineering, drawing, and architecture all use parallel and perpendicular lines. Other than that, it is an important topic because you are learning how to apply the language and tools of mathematics to an intuitive system. These topics have proven important in the history of human kind and also many before you have shown that by learning about parallel and perpendicular lines, one learns how to use math and logic. It is doubtful that you can make a living off of parallel and perpendicular lines, but if you can't understand parallel and perpendicular lines, then I worry about your future.

Lines of latitude run east-west as circles parallel (or horizontal lines) to the equator. Latitude measures the angle in degrees north or south from the equator where the equator is located at 0 degrees.

If you mean points of (-3, -2) and (4, -2) then the slope is 0

What is the meaning of the safety symbol shown below?

Because they never move closer to each other; they are always the exact same distance apart. They don't meet by definition. If the lines in question ever met you would have to come up with a new word to describe them. Basically, the word parallel is an agreement between everybody practicing Euclidian geometry. We agree to call two lines parallel if they meet the following two criteria: 1. A plane exists on which both lines can exist 2. They never meet If only #1 is met the lines are called "coplanar" (actually it can be shown that any two lines that do meet must be coplanar) If only #2 is met the lines are called "skew"
