The line formed by the infinite number of points with zero latitude is commonly called the "equator".
Those are the Latitude lines.
A solid line of thunderstorms is called a squall line.
Well one line of latitude is called the 'equator'.
Because the band is broken by colorless gaps
the answer
A line along which the cost of something -- usually a combination of two factors of production -- is constant. Since these are usually drawn for given prices, which are therefore constant along the line, an isocost line is usually a straight line, with slope equal to the ratio of the (factor) prices.
Isocost Lines Recall that a universally accepted objective of any firm is to maximise profit. If the firm maximises profit, it will necessarily minimise cost for producing a given level of output or maximise output for a given level of cost. Suppose there are 2 inputs: capital (K) and labour (L) that are variable in the relevant time period. What combination of (K,L) should the firm choose in order to maximise output for a given level of cost? If there are 2 inputs, K,L, then given the price of capital (P k ) and the price of labour (P L ), it is possible to determine the alternative combinations of (K,L) that can be purchased for a given level of expenditure. Suppose C is total expenditure, then C= P L * L + P k * K This linear function can be plotted on a graph. ISOCOST K C/P k A B O C/P L L • N • P Figure 7.7: Isocost line If only capital is purchased, then the maximum amount that can be bought is C/P k shown by point A in figure 7.7. If only labour is purchased, then the maximum amount of labour that can be purchased is C/P L shown by point B in the figure. The 2 points A and B can be joined by a straight line. This straight line is called the isocost line or equal cost line. It shows the alternative combinations of (K,L) that can be purchased for the given expenditure level C. Any point to the right and above the isocost is not attainable as it involves a level of expenditure greater than C and any point to the left and below the isocost such as P is attainable, although it implies the firm is spending less than C. You should verify that the slope of the isocost is 1 - k L k L P P P C * P C ∆ L ∆ K EXAMPLE : Consider the following data: P L = 10, P k = 20 Total Expenditure = 200. Let us first plot the various combinations of K and L that are possible. We 1 The nagative sign is due to the fact that the slope of the isocost is negative.15 consider only the case when the firm spends the entire budget of 200. The alternative combinations are shown in the figure (7.8).

What will happen if labour becomes more expensive say P L increases to 20? Obviously with the same budget the firm can now purchase lesser units of labour. The isocost still meets the Y-axis at point A (because the price of capital is unchanged), but shifts inwards in the direction of the arrow to meet the X-axis at point C. The slope therefore changes to -1. You should work out the effect on the isocost curve on the following: (i) decrease in the price of labour (ii) increase in the price of capital (iii) decrease in the price of capital (iv) increase in the firms budget with no change in the price of labour and capital
Any line belonging to the system of parallel lines to the given objective function for various values f is called ISO - profit line
The end of the railway line is called the terminus. It can also be called the terminal. It is the place where the line ends or terminates.

Gross Profit is the difference between money received from sales and the money you have paid out for the goods you sold. Operating Profit is the gross profit less any expenses you incurred while trading such as rent for premises, electricity, telephone bills Net profit is the operating profit less any tax and interest and dividend paid. The net profit is sometimes called "bottom line profit" Hope this clears things up!
A figure which is identical on both sides of LINE is said to be symmetrical about that line and that line is called line of symmetryor axsis of symmetry. Line of symetry is also called 'mirror line'

A line of constant longitude is often referred to as a 'meridian'.
A line, although often a segment is also called a tangent.
