# Straight Lines Assignments/DPPs

The seemingly simple concept of Straight Lines in coordinate geometry plays a fundamental role in Class 11 mathematics and lays a strong foundation for success in the Joint Entrance Examination (JEE). Understanding the properties of straight lines and their equations opens the door to solving diverse geometrical problems across multiple topics in the exam.

## Overview of Permutation and Combination Class 11

#### Key Formulas You Need to Know:

• Slope-intercept form: y = mx + c (where m is the slope and c is the y-intercept)
• Point-slope form: y – y1 = m(x – x1) (where (x1, y1) is a point on the line and m is the slope)
• Two-point form: (y – y1) / (y2 – y1) = (x – x1) / (x2- x1) (where (x1, y1) and (x2, y2) are two points on the line)
• Distance between two points: √[(x2 – x1)^2 + (y2 – y1)^2]

#### Straight Lines in the JEE

The JEE tests your comprehensive understanding of straight lines through various question types, including:

• Finding equations of lines: You may need to determine equations based on given information like slope and a point, or two points.
• Lines and their relationships: Questions might test your knowledge of parallel, perpendicular, and intersecting lines.
• Applications in other areas: Straight lines often appear in problems related to circles, parabolas, and other geometrical figures.
