What are intercepts in the context of linear equations and graphs?
What are intercepts in the context of linear equations and graphs?
Intercepts are the points where a straight line crosses the x-axis (x-intercept) or the y-axis (y-intercept).
What is the difference between x-intercept and y-intercept?
What is the difference between x-intercept and y-intercept?
The x-intercept is the point where the line crosses the x-axis, while the y-intercept is the point where the line crosses the y-axis.

Study Notes
Intercepts in Linear Equations and Graphs
- Intercepts are points where a line crosses the x-axis (x-intercept) or the y-axis (y-intercept).
X-intercept vs. Y-intercept
- X-intercept: The point where the line crosses the x-axis. The y-coordinate of this point is always 0.
- Y-intercept: The point where the line crosses the y-axis. The x-coordinate of this point is always 0.
Uniqueness of Intercepts for Straight Lines
- A straight line will only have one x-intercept and one y-intercept.
Calculating the Gradient
- Calculating the gradient can be difficult if the points provided are not easily identifiable on a graph or if the line is not neatly drawn.
Intercepts for Other Types of Lines
- Parabolas and polynomials can have multiple x-intercepts and y-intercepts.
Locating Intercepts
- X-intercept: Located on the x-axis, where y = 0
- Y-intercept: Located on the y-axis, where x = 0
Axes Representation
- X-axis: Represents the horizontal axis
- Y-axis: Represents the vertical axis
