What is a linear equation?

A linear equation is an algebraic equation that represents a straight line when graphed. It typically takes the form 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. The solution to a linear equation is a set of values that satisfy the equation when substituted into it.

How do you solve a linear equation with one variable?

To solve a linear equation with one variable, you need to isolate the variable on one side of the equation. This is done by performing the same operations on both sides of the equation to keep it balanced. Start by simplifying both sides of the equation by combining like terms and then use inverse operations such as addition, subtraction, multiplication, and division to isolate the variable. Once the variable is isolated, you can solve for its value and find the solution to the linear equation.

What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is y = mx + b, where y represents the dependent variable, x represents the independent variable, m represents the slope of the line, and b represents the y-intercept, which is the point where the line intersects the y-axis.

How do you graph a linear equation?

To graph a linear equation, first convert the equation to the slope-intercept form (y = mx + b) where 'm' is the slope and 'b' is the y-intercept. Then, plot the y-intercept on the y-axis and use the slope to find another point on the line by moving up (if the slope is positive) or down (if the slope is negative) and to the right by one unit. Connect the two points with a straight line to complete the graph of the linear equation.

What is the point-slope form of a linear equation?

The point-slope form of a linear equation is given by the equation \(y - y_1 = m(x - x_1)\), where \(m\) is the slope of the line, and \((x_1, y_1)\) are the coordinates of a point on the line. This form is useful for finding the equation of a straight line when the slope of the line and a point on the line are known.

What is the standard form of a linear equation?

The standard form of a linear equation is Ax + By = C, where A, B, and C are constants, and A and B are not both zero.

How do you find the x-intercept of a linear equation?

To find the x-intercept of a linear equation, set the y-coordinate equal to zero and solve for x. This means you are finding the point where the line crosses the x-axis, so the y-value at this point will be zero. By setting y=0 and solving for x, you can determine the x-coordinate of the x-intercept.

How do you find the y-intercept of a linear equation?

To find the y-intercept of a linear equation, you can set x equal to 0 and solve for y. The y-intercept is the point where the line crosses the y-axis, so when x is 0, you are left with the value of y at that point on the graph. This y-value represents the y-intercept of the linear equation.

How do you solve a system of linear equations?

To solve a system of linear equations, you first need to write the equations in standard form. Then, you can use methods like substitution, elimination, or matrices to find the values of the variables that satisfy all the equations simultaneously. Finally, you can check your solution by substituting the values back into the original equations to ensure they are correct.

What are real-world applications of linear equations?

Linear equations have numerous real-world applications, such as in determining sales and expenses for businesses, calculating depreciation of assets over time, analyzing population growth, predicting trends in stock prices, designing electrical circuits, optimizing production schedules, and solving problems in physics and engineering related to motion, heat transfer, and fluid dynamics. These equations provide a basic framework for modeling relationships between variables and making informed decisions based on mathematical relationships.
