What is a linear equation?

A linear equation is an algebraic equation that represents a straight line when plotted on a graph. It consists of variables raised only to the first power, with constants and coefficients multiplying the variables. The general form of a linear equation is y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.

How can you determine if two linear equations are parallel?

Two linear equations are parallel if they have the same slope but different y-intercepts. To determine if two linear equations are parallel, you can put them into slope-intercept form (y = mx + b) where "m" represents the slope. If the slopes of the two equations are equal, then the lines represented by the equations are parallel. If the slopes are different, the lines are not parallel.

What is the difference between a linear equation and a linear inequality?

A linear equation is a mathematical statement that asserts an equality between two algebraic expressions, while a linear inequality is a mathematical statement that asserts the relationship between two algebraic expressions using inequality symbols such as less than (<), greater than (>), less than or equal to (?), or greater than or equal to (?). In other words, a linear equation represents a specific point or line on a graph, while a linear inequality represents a region or area on a graph.

How can you graph a linear equation?

To graph a linear equation, start by isolating the y variable and rewriting the equation in the slope-intercept form y = mx + b where m is the slope and b is the y-intercept. Plot the y-intercept on the y-axis, then use the slope to find another point on the line. Connect these points to sketch a straight line that represents the linear equation on the coordinate plane. Make sure to use a ruler or straight edge for accuracy.

What is the solution to a linear equation?

The solution to a linear equation is the value of the variable that makes the equation true when substituted into the equation. In other words, it is the value that satisfies the equation and makes both sides equal to each other.

How can you write a linear equation in slope-intercept form?

To write a linear equation in slope-intercept form, start with the equation y = mx + b, where m represents the slope of the line and b represents the y-intercept (the point where the line crosses the y-axis). To find the slope, calculate the change in y divided by the change in x between two points on the line. Once you have the slope and the y-intercept, substitute these values into the equation y = mx + b to form the linear equation in slope-intercept form.

What is a system of linear equations?

A system of linear equations is a set of two or more linear equations that involve the same variables. The goal is to find the values of the variables that satisfy all the equations simultaneously, representing the intersection point of the lines or planes defined by the equations. This is typically solved using methods such as substitution, elimination, or matrices.

What does it mean if two linear equations have no solution?

If two linear equations have no solution, it means that the equations are parallel lines and do not intersect at any point in the coordinate plane. This occurs when the slopes of the two lines are equal but their y-intercepts are different, resulting in lines that run parallel to each other without ever crossing.

How can you solve a linear inequality algebraically?

To solve a linear inequality algebraically, you would isolate the variable on one side of the inequality sign and perform the same operations on both sides of the inequality. Remember to reverse the inequality sign when multiplying or dividing by a negative number. Once you have found the value or range of values for the variable that satisfy the inequality, you can represent the solution on a number line or in interval notation.

How can you solve a system of linear inequalities graphically?

To solve a system of linear inequalities graphically, plot each inequality on a coordinate plane to create shading areas representing the feasible region for each inequality. The solution to the system of inequalities is the overlapping shaded region where all inequalities overlap. This region includes points that satisfy all inequalities simultaneously. The feasible region visually shows the solution space for the system of linear inequalities.
