## The Lesson

The y-intercept of a line is the y-coordinate of the point where the line crosses the y-axis. Imagine a line is drawn on a graph. We can find the y-intercept of the line.## How to Find the Y-Intercept of a Line

Finding the y-intercept of a line is easy.## Question

Find the y-intercept of the line shown below.## Step-by-Step:

# 1

Find where the line crosses the y-axis.

# 2

Read off the y-coordinate of the point where the line crosses the y-axis. In our example, the line crosses the y-axis at a y-intercept of

**1**.## Answer:

The y-intercept is**1**.

## Positive, Zero and Negative Y-Intercepts

A positive y-intercept means the line crosses the y-axis**above**the x-axis:

A zero y-intercept means the line crosses the y-axis at the origin:

A negative y-intercept means the line crosses the y-axis

**below**the x-axis:
