The '''x-intercept''' is the x-coordinate of the point at which a [[line]] intersects the [[x-axis]]. If the line is represented in the point-slope form, i.e., <math> y = m \cdot x +b</math> and <math>m \neq 0</math>, then the ''x-intercept'' is <math>-b/m</math>. if <math> m = 0</math>, the line doesn't cross the x-axis (case <math>b \neq 0</math>) - so there is no intersection, or the line is identical to the x-axis (case <math>b = 0</math>).
