Terminology

x-intercept

y-intercept

Finding x- and y-Intercepts

To find the x-intercept, let y = 0 and solve for x.

To find the y-intercept, let x = 0 and solve for y.

 

Vertical Line

The graph of x = c, where c is a real number, is a vertical line with x-intercept c.

 

Horizontal Line

The graph of y = c, where c is a real number, is a horizontal line with y-intercept c.
