Linear Function

[ad_1]

There are many key features that you will learn during math career. The first and most basic function is a linear function. A linear function is used to describe the relationship of a straight line. This can be any straight line at any angle or any position. The general form of these operations is as follows;

y = m * x + b

Lets take a look at what all these terms mean. It is important to have a thorough understanding of what each of them means in mathematics and understanding.

First off we can bring our two variables in this equation x and y. X is the independent variable and it is represented on the horizontal axis of the graph. Y is the dependent variable (since its value depends on the value of x) and is represented on the vertical axis of the graph.

The letter ‘m’ is the slope. Graphically, this will give you the angle of the line. The higher the slope, the steeper the angle with the x-axis. The slope can be determined which of the two place on the line. You will simply sub force of the equation ;.

m = y2 – y1 / (x2 – x1)

This calculation is usually fairly easy and can be done on a calculator

last term, b, is the intersection of the line . This is the point where the line crosses the y-axis. If you have a graph of the line you can simply read values ​​directly from the graph. If you have the slope, you can prepare in every place on the line, rearrange and solve algebraically for the intersection.

So as you can see is a linear function not very complicated. It is a good place to start when learning about operations.
