A: ### Quick Answer

**According to the Math Planet, a coordinate plane is a two-dimensional number line that is composed of a horizontal line called the x-axis and a vertical line called the y-axis.** These two lines are perpendicular with each other and intersect at a point called the origin.

Math Open Reference states that points, lines and curves can be plotted on a coordinate plane. Moreover, the two axes divide the coordinate plane into four parts called quadrants. The top right part is called the first quadrant and on the top left is the second quadrant. The third quadrant is located below the second quadrant, and the fourth quadrant is below the first quadrant.

- Q:
## What is a vertical line?

A:

Full Answer >**A vertical line is one that is parallel to the y-axis of a graph.**A vertical line is also perpendicular to the x-axis of the same graph, which means that the value of the x-coordinate for a vertical line does not change.Filed Under: - Q:
## How can you represent diminishing returns by using a graph?

A:Diminishing returns is graphed by assigning the input factor to the x-axis and assigning the output, or product, to the y-axis. The total product curve is the total number of units produced per units of input. The marginal product curve is the marginal product generated per units of input. Diminishing returns is reflected at the point where the marginal product curve has a negative slope.

## What is the method of graphing imaginary numbers?

A:Imaginary numbers are graphed on the complex plane as part of complex numbers where the y-axis represents the imaginary number values and the x-axis represents the real number values. Complex numbers are of the form "x" + "yi" where "yi" is the imaginary number value plotted on the y-axis.

## What is the difference between horizontal and vertical analysis?

A:

Full Answer >**Horizontal analysis makes comparisons of numbers or amounts in time while vertical analysis involves displaying the numbers as percentages of a total in order to compare them.**Both are useful financial analysis techniques that calculate relationships between figures in balance sheets and income statements.Filed Under:
