So the x-intercept of the line is - 3. Download Definition Of X Intercept In Math - A. Since the x-intercept is a point we will want to write it in point notation.
Lines always have both an x and y-intercept unless the line is a horizontal or a vertical line.
We Also Know That No Matter Where You Are On The X-Axis The Y Value Is. If a line is parallel to the y-axis its x-intercept is not defined. The y-coordinate of the point where a line intersects the x-axis is 0 So the x-intercept of a line can also be found by substituting y 0 in the equation of the line. We Also Know That No Matter Where You Are On The X-Axis The Y Value Is.
