# Three Ways How to Graph a Line

Graphing a line in the xy-axis is one of the most basic skills in algebra that you should learn. In this lesson, we are going to go over **three methods** that are commonly used. Learn each method and you’ll be able to decide which one works better depending on the given problem.

I have created separate lessons for each. Click “View Lesson Here” to get to the specific tutorial.

**Method 1: Constructing a Table of Values**

This is the most straightforward method in graphing a line. What we need to do is to select some values of *x* and then evaluate those values in the given equation to get the corresponding values of y. Finally, plot those points in the xy-axis, and connect them with a straight edge.

**Method 2: Using the Slope and y-intercept (y = mx+b)**

The first step is to make sure that the equation of the line is in the Slope-Intercept Form, that is ** y = mx + b**.

- Start by plotting the y-intercept which is (0,
*b*). - Find another point using the slope (
*m*) with the y-intercept at the reference point. - Connect the two points with a ruler.

**Method 3: Connecting the x and y-Intercepts**

Remember, we only need two points to graph a line. With that idea, we take advantage of the two “convenient” points which can easily be solved algebraically from the equation of the line; namely, the x-intercept (*x*, 0) and y-intercept (0, *y*).

- To solve for the x-intercept, let
*y*= 0 then solve for*x*. - To solve for the y-intercept, let
*x*= 0 then solve for*y*. - Connect the two points using a ruler.
