**Description:**

This test consist of 10 questions.Students should ideally take 10 minutes to complete the test. This test is useful for those students who are preparing for IIT JEE, AIEEE or any other engineering entrance test. This test cosist of questions from Straight Line which, in general, is focused in AIEEE and IIT JEE. Last year - 6 questions was asked from this chapter in AIEEE. In Straight Line slopes, distance from a point to straight line are key topics and mostly application based questions are asked.

**Discussion**

if a st. line passes through the point (1/5,1/5) and ab=1/6 where a,b are the intercepts of the line on the co-ordinate axes , then the equation of the line is
