What's a example and definition of a linear exspression
A linear expression is an algebraic expression in which the variables are raised to the power of 1 and do not contain any exponents or radicals. It is an expression with a degree of 1.
Example:
3x + 2y - 5
In this example, both x and y are variables raised to the power of 1. The coefficients of x and y are 3 and 2 respectively. The constant term is -5. Overall, this is a linear expression.
A linear expression is an algebraic expression in one variable that represents a line on a graph. It consists of a constant term (a number), multiplied by the variable, with no exponents or roots involved.
An example of a linear expression is:
2x - 3
In this expression, "2x" represents the coefficient (2) multiplied by the variable x, and "-3" represents the constant term.
The term "linear" is used because when plotted on a graph, it forms a straight line.
