Understanding X-intercepts
In mathematics, particularly in algebra, the x-intercept of a line or curve is the point where the graph intersects the x-axis of the coordinate system. At this point, the y-coordinate is always zero. For a linear equation in the slope-intercept form y = mx + b, the x-intercept can be found by setting y = 0 and solving for x.
The formula to calculate the x-intercept is: x = -b / m where 'm' is the slope and 'b' is the y-intercept. This calculator simplifies this process and provides a visual representation of the line and its x-intercept.
- Slope (m): Represents the steepness and direction of the line.
- Y-intercept (b): The point where the line crosses the y-axis (when x = 0).
- X-intercept: The point where the line crosses the x-axis (when y = 0).
