Identifying the y-intercept from a graph

Front

What is the definition of the y-intercept in a graph?

Back

The y-intercept is the point where a line crosses the y-axis, indicating the value of y when x is zero.

What does a negative y-intercept indicate about a line on a graph?

Back

A negative y-intercept indicates that the line crosses the y-axis below the origin.
