Functions

X- and Y-Intercepts

In a Cartesian plane, the coordinates of the intersections of a curve with the axes.
If a curve intersects with the x-axis at the point (a, 0) and the y-axis at the point (0, b), a is the x-intercept and b is the y-intercept. Coordonee origine

Example

In this Cartesian plane, the x- and y-intercepts of the line represented in orange, for which the equation is y = 3x + 2 are [latex](−\frac{2}{3}, 0)[/latex] and [latex](0, 2)[/latex]. The x-intercept of this line is x = [latex]−\frac{2}{3}[/latex] and the y-intercept is y = 2.

Educational Note

Note that the x- and y-intercepts of the graph of a function are ordered pairs of numbers, while the x- and y-intercepts are numbers.
