## What is a straight line in maths class 11?

A straight line is defined as a line traced by a point travelling in a constant direction with zero curvature. In other words, the shortest distance between two points is called a straight line.

**What is straight line formula?**

The general equation of a straight line is y = m x + c , where is the gradient and the coordinates of the y-intercept. Look at the National 4 straight line section before continuing. We can find the equation of a straight line when given the gradient and a point on the line by using the formula : y − b = m ( x − a )

### What is a straight line answer?

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point. A straight line does not have any curve in it.

**How do you find the equation of a line in Class 11?**

Thus General Equation of Straight line is Ax + By + C = 0, where A, B and C are real constants such that A and B are not zero simultaneously. Numerical: Equation of a line is 3x – 4y + 10 = 0. Find its (i) slope, (ii) x – and y-intercepts.

#### What is a straight line called?

A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no “wiggles” anywhere along its length. While lines are intrinsically one-dimensional objects, they may be embedded in higher dimensional spaces. Harary (1994) called an edge of a graph a “line.”

**What is normal form in straight lines?**

A normal to a line is a line segment drawn from a point perpendicular to the given line. Let p be the length of the normal drawn from the origin to a line, which subtends an angle ø with the positive direction of x-axis as follows. x Cos ø + y Sin ø = p.

## What is straight line example?

What is a Straight Line? A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.

**How do you write straight lines?**

5 Tips for Writing in a Straight Line

- Use the top edge of the paper as your guide.
- Use a ruler and a pencil to place some dots.
- Practice your straight line writing first.
- Use lined paper underneath your stationery.
- Go with the flow.

### What is normal form of straight line?

(i) The equation of a, straight line in the form of x cos α + y sin α = p is called its normal form.

## What is Chapter 10 of NCERT solutions for Class 11 Maths?

Some of the topics discussed in Chapter 10 of NCERT Solutions for Class 11 Maths are as follows: Slope (m) of a non-vertical line. If a line makes an angle á with the positive direction of x-axis, then the slope of the line is given by m = tan α, α ≠ 90°. Slope of a horizontal line is zero and slope of vertical line is undefined.
