i is the Imaginary Unit, equal to sqrt(-1). So i and any real number multiplied by i will all be imaginary numbers. Here are some: i, -i, 5i, -3i, i*pi, etc.

Because it's not. However, if you were to take the square root of -16, the answer would be 4i, which is an imaginary number, considered imaginary because multiplication of a real number by itself cannot equal a negative number.
I don't know the full answer but I got two letters I know: r and t
This imaginary line is called the equator. On the two equinoxes each year (around March 20th and September 23rd), the sun is directly over the equator, causing nearly equal lengths of day and night worldwide. This phenomenon is known as the equinox.

Isohyets are the term used for imaginary lines joining places of equal rainfall.
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
The imaginary line that cuts the earth into two equal parts is called the equator. It is an imaginary circle around the Earth that is equidistant from the North and South poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
an imaginary line, joining the equal elevations of the points

The mathematical importance of an imaginary number is to allow the result of a square root of the imaginary number to equal a negative number. One can find more extensive information on imaginary numbers and their importance on the Wikipedia website.

Counter line is the imaginary line joining the equal altitudes (Elevations).
