What is the equation of line Class 11?

General equation of a line is ax + by + c = 0. The inclination of angle θ to a line with a positive direction of X-axis in the anti-clockwise direction, the tangent of angle θ is said to be slope or gradient of the line and is denoted by m.

How do you find the slope of a pair of straight lines?

The equation that is derived for any straight line is called a linear equation and it can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.

Is straight line easy?

A straight line is one of the easiest constructions to make in geometry. With a sheet of blank paper, a pencil, and a straightedge, you can construct a line easily: Draw two dots on the paper, some distance from each other; these are Points.

What is slope in straight line?

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’.
