What is a linear function and how do we graph them?
This post will help you with graphing linear functions in Prelim Standard Math. A linear function makes a straight line when graphed on a number plane. To graph a linear function, you need to follow these simple steps:
- Construct a table of values with the independent variable as the first row and the dependent variable as the second row
- Draw a number plane with the independent variable on the horizontal axis and the dependent variable as the vertical axis. Plot the points
- Join the points to make a straight line
How do you construct a linear function from a table of values?
The videos below explain how to construct a linear function from a table of values, and how the table of values helps us construct a variety of different functions.
