RD Sharma Solutions Class 12 Straight Line In Space

RD Sharma Solutions Class 12 Chapter 28

A line extending on both sides till infinity without any no curves is called a straight line. It is an object in geometry which is characterized by zero width object and extends in opposite directions without any ends. A straight line was the first topic to be explained by Euclid- a founder of Geometry.

The equation of straight lines can be expressed in the form:

y = mx + b

Where y is the intercept

x is how far along

m is the slope or the gradient.

b is the intercept of y.

For example:

The line y = 3x + 5 has

Slope m=3 and y-intercept b = 5.
