Front

How can you represent the y-intercept on a graph?

Back

The y-intercept can be represented as the point where the line crosses the y-axis, typically written as (0, b).

Back

The y-intercept is -2.

Front

If a line has a slope of 0, what can you say about its y-intercept?

Back

If the slope is 0, the line is horizontal and the y-intercept is the constant value of y for all x.
