What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) where b is the value of the y-intercept.

How can you determine the y-intercept from a table of values?

Back

The y-intercept can be found by identifying the value of y when x is 0.
