Topics Covered in Chapter 23 - The Straight Lines

  • A straight line has not been curved or bent in any way. All of the fundamental and advanced ideas connected to straight lines are addressed in this session. This lesson is also available in PDF format, which allows students to refer to the principles while offline.

  • A line is a simple geometric object that is defined as a zero-width object that extends on both sides. A straight line has no bends. A straight line is a line that stretches to infinity on both sides and has no bends.


Straight Line Equation

All points on the curve are satisfied by the relationship between variables x and y. The equation of a straight line is axe + by + c = 0. The variables x and y are variables, and the constants a,b, and c are constants.


Origins Shifting

Let's say the origin is moved to point O' (h, k). If P(x, y) are the coordinates of a point on old axes, and P'(X, Y) are the coordinates of the same points on new axes, x = X + h, and y = Y + k.


Straight Line

If two locations on a curve are chosen such that every point on the line segment connecting any two points on the curve lies on the curve, it is said to be a straight line. A line's general equation is axe + by + c = 0.


Line Slope or Gradient

The slope or gradient of a line is defined as the inclination of an angle to a line with a positive X-axis in the anti-clockwise direction, denoted by m.


The Equation of a Line in Various Forms

The equation of a line is y = k if it is at a distance of k and parallel to the X-axis.

The equation for a line parallel to the Y-axis at a distance of c from the Y-axis is x = c.

Slope-intercept form: y = mx + c is the equation of a line with slope m and an intercept c on the y-axis.

One point-slope form: y – y1 = m (x – x1) is the equation of a line that passes through the point (x1, y1) and has a slope of m.

FAQs on RD Sharma Class 11 Solutions Chapter 23 - The Straight Lines (Ex 23.5) Exercise 23.5

1. How is the position of points relative to a given line according to RD Sharma Class 11 Solutions Chapter 23 - The Straight Lines (Ex 23?

We’ll assume and let the equation of the given line be ax + by + c = 0 and further, let the coordinates of the two given points be P(x1, y1) and Q(x2, y2). To understand further, we’ll let the two points be on the same side of the straight line ax + by + c = 0, If ax1 + by1 + c and ax2 + by2 + c have the same sign. Now, the two points are on the opposite sides of the straight line ax + by + c = 0, If ax1 + by1 + c and ax2 + by2 + c have opposite signs. 

2. What are the various forms of the equation of a line according to RD Sharma Class 11 Solutions Chapter 23 - The Straight Lines (Ex 23)?

The equation of a line is y = k if it is at a distance of k and parallel to the X-axis. The equation for a line parallel to the Y-axis at a distance of c from the Y-axis is x = c. Form of the slope-intercept: y = mx + c is the equation for a line with slope m and an intercept c on the y-axis. One point-slope shape is as follows: y – y1 = m (x – x1) is the equation of a line that passes through the point (x1, y1) and has a slope of m.

3. What are some other resources that I can refer to while preparing for Chapter 23 - The Straight Lines?
