y-intercept
Where graphs begin
The y-intercept is the point where a line or curve crosses the vertical axis on a graph—the value of y when x equals zero.
In the slope-intercept equation y = mx + b, the y-intercept is b.
The line has a y-intercept of 3, meaning it crosses the y-axis at the point (0, 3).
