- Sample Linear Graph
Linear graphs are graphical representations of linear equations. They are one of the most common forms of graphs which are plotted for a wide variety of purposes. Linear graphs must be plotted in a slope-intercept form within rectangular coordinates. Once the technical aspect of graph plotting is understood, plotting linear graphs becomes easy and convenient.
A linear graph is a straight line graph whose slope is the equation. A linear graph helps depict a linear relationship by means of which when one value goes up, the other makes a change by the same amount every time.
Linear graphs should be titled clearly. The axes must be clearly labeled and a key with the value of each unit must be mentioned. This is the most important part of a linear graph. If the ratio and the key are not mentioned correctly, linear graphs will yield faulty results.
The advantage of a linear graph over a linear equation is that the former is much more vivid and conveys information in a superior manner. Even for those who are unable to solve linear equations, a linear graph can convey information easily.
Linear graphs are flexible and adaptable. Once the data can be resolved into a linear equation, and the slope is calculated, forming linear equation becomes simple enough.
