# X and Y Intercepts of a Line

When a straight line is represented graphically the following two main attributes will come out: the -intercept and the -intercept of the straight line. These two concepts are very simple and easy to understand when we draw a straight line graphically.

The -intercept occurs when we draw a straight in a Cartesian plane, i.e. -plane, and the straight line cuts the -axis at one point, say . This point of intersection is called the -intercept of a straight line and at the point value of the -axis is zero, i.e. . The -intercept is usually represented by an ordered pair: .

Similarly, the -intercept occurs when the straight line cuts the -axis at one point, say . This point of intersection is called the -intercept of a straight line and at this point value of the X-axis is zero, i.e. . The -intercept is usually represented by an ordered pair: .

Algebraically we can find the -intercept and -intercept of a straight line by setting the values and respectively.

__Example__**:** Find the - and -intercepts of the given straight line:

To find the -intercept put in the above equation of a straight line:

Therefore, the -intercept is .

Similarly, to find the -intercept put in the above equation of a straight line:

Therefore, the -intercept is .
