Linear equations may be solved by isolating the variable or variables. Solving linear equations involves undoing whatever operations have been done to the variable and putting the variable alone on one side of the equal ... More »

To write the equation of a line, find the slope and the y-intercept, and incorporate them into slope-intercept form. If you do not know the slope and the intercept, you can also use point-slope form, as long as you have ... More »

Linear equations are used to solve problems involving distance, speed and time, especially in transportation and travel. They are also used to solve problems of weight, mass and density. More »

Linear algebra originated as the study of linear equations and the relationship between a number of variables. Linear algebra specifically studies the solution of simultaneous linear equations. More »

Linear graphs represent the behavior of dependent variables that sit along a straight line with regard to independent variables, while nonlinear graphs represent variables that don't. Common functions that result in nonl... More »

To solve equations with variables on both sides, move the constants to the right side of the equation, simplify, move the variables to the left side and simplify. If the variable is negative, multiply both sides by -1 to... More »

Basic problems in Algebra I typically teach students to solve one-step equations to find variables with addition, subtraction, multiplication and division. From there, students learn to solve two-step equations. More »
