Y intercept
Set x equal to zero and solve for y
In mathematics, a y-intercept is the point where a line or a curve intersects the y-axis on the coordinate plane. It is the point where x = 0. The y-intercept is denoted by the coordinates (0, y) where ‘y’ represents the value of the y-coordinate of the point.
For example, given the equation of a line in slope-intercept form y = mx + b, where ‘m’ is the slope and ‘b’ is the y-intercept, the y-intercept is the value of ‘b’. If the equation of the line is y = 2x + 3, then the y-intercept is the point (0,3) because when x=0, y=3.
In summary, the y-intercept is the point of intersection between a curve or a line and the y-axis on the coordinate plane where the x-coordinate is zero.
