A linear equation is an algebraic equation that represents a straight line on a coordinate plane.

It is an equation in which the highest power of the variable(s) is one.

The general form of a linear equation is:
ax + by = c

Explanation: Here, the given image shows that x and y are variables. The constants a and b represent the coefficients of the variables x and y, respectively, while c is the constant term.

Linear equations with one variable are algebraic equations that involve only one variable raised to the first power (i.e., it’s not squared, cubed, etc.).

The general form of a linear equation with one variable is:
ax + b = c

Explanation: Here, the given image shows that a is the coefficient of x, b and c are constants, and x is the variable.
