Linear Polynomial

A linear polynomial is a polynomial of degree 1, which means it has a highest power of 1 for its variable. It can be written in the form:

ax + b

Where 'a' and 'b' are constants, and 'x' is the variable. The value of 'a' cannot be zero for it to be a linear polynomial.

Understanding the Components:

Coefficient (a): The coefficient 'a' represents the slope or gradient of the linear polynomial. It determines the rate of change of the polynomial.

Constant (b): The constant 'b' represents the y-intercept of the linear polynomial. It is the point where the polynomial intersects the y-axis.

Graphical Representation:

A linear polynomial represents a straight line when graphed on a Cartesian plane. The coefficient 'a' determines the slope of the line, while the constant 'b' determines the y-intercept.

Example:

Consider the linear polynomial 3x + 2. Here, the coefficient 'a' is 3 and the constant 'b' is 2. This polynomial represents a line with a slope of 3 and a y-intercept of 2.
