Isobar for atmospheric pressure, isotherm for temperature, or contour for height above (below) sea level.
City maps, the squares or grids represent one square mile. On larger maps they can indicate townships, counties, or land parcels.
The equation x=c where c is a constant is the equation of a vertical line. It can't be a function but it is linear so the answer is no. For example, the vertical line produced by the linear equation x = 3 does not represent a function. We cannot write this equation so that y is a function of x because the only x-value is 3 and this "maps" to every real-number y.
A flow line for a map on a vector field is a path such that .
Only if each of the other maps is to the same scale as your example one. If not... no!
y=x
the blue line represents Lakes, Streams , canal and mainly just water
An isoline is used on maps to represent points of equal value. The isoline for air pressure is an isobar.
