When represents the straight line graphically the two main attributes of will come out, one is the -intercept and the other is -intercept of the straight line. These two concepts are very simple and easy to understand when draw straight line graphically.

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

Similarly, -intercept can be found where the straight line cuts the -axis at one point say and this point of intersection is called -intercept of a straight line and at this point value of X-axis is zero i.e. . -intercept is usually represented by an ordered pair .

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

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

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

Therefore, -intercept is .

Similarly To find -intercept put in the above equation of straight line as

Therefore, -intercept is .
