y-intercept

The **y-intercept** is the point where a graph crosses the y-axis on a coordinate plane. It represents the value of y when the independent variable x is zero. In linear equations, the y-intercept is a key component of the equation in slope-intercept form, expressed as ( y = mx + b ), where ( b ) denotes the y-intercept. Understanding the y-intercept is essential for graphing linear functions, interpreting data trends, and solving algebraic problems.
