What is a linear equation?

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable raised to the first power, with no exponents higher than one. It represents a straight line on a graph and can be written in the form ax + b = 0, where a and b are constants and x is the variable.

How can you determine the slope of a linear equation?

To determine the slope of a linear equation, you can look at the coefficient of the variable that is raised to the first power. It represents the rate at which the line is rising or falling. If the equation is in the form y = mx + b, where m is the slope and b is the y-intercept, then the coefficient m is the slope of the line.

What is the y-intercept of a linear equation, and how can you find it?

The y-intercept of a linear equation is the point where the graph intersects the y-axis. It represents the value of y when x is zero. To find the y-intercept of a linear equation, you can set x to zero and solve for y. The resulting value of y will be the y-intercept of the equation.

How do you graph a linear equation using the slope-intercept form?

To graph a linear equation in slope-intercept form (y = mx + b), start by identifying the y-intercept (b) as a point on the y-axis. Then, use the slope (m) to determine a second point by moving up or down based on the rise and left or right based on the run from the initial point. Connect these two points with a straight line to complete the graph of the linear equation.

How do you graph a linear equation using the x-intercept and y-intercept?

To graph a linear equation using the x-intercept and y-intercept, you start by plotting the x-intercept point on the x-axis and the y-intercept point on the y-axis. Then, connect these two points with a straight line to represent the linear equation. The x-intercept is where the line crosses the x-axis (y = 0) and the y-intercept is where the line crosses the y-axis (x = 0). By connecting these two points, you create 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 y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line. This form is useful for writing the equation of a line when you know the slope and a point on the line, making it easy to find the equation of a straight line in a fast and convenient way.

How can you find the equation of a line given two points on the line?

To find the equation of a line given two points on the line, you can first calculate the slope of the line using the formula (y? - y?) / (x? - x?), where (x?, y?) and (x?, y?) are the coordinates of the two points. Once you have the slope, you can use one of the two points and the slope to form the equation of the line in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. Substituting the slope and the known point into the equation will give you the full equation of the line.

How can you tell if two linear equations are parallel or perpendicular?

Two linear equations are parallel if their slopes are equal and perpendicular if the product of their slopes is -1. To determine this, you can compare the slopes of both equations. If the slopes are the same, the lines are parallel. If the product of the slopes is -1, the lines are perpendicular.

How do you solve a system of linear equations graphically?

To solve a system of linear equations graphically, you would graph each equation on the same coordinate plane, then find the point where the lines intersect. This point represents the solution to the system of equations. If the lines are parallel and do not intersect, then there is no solution. If the lines overlap and coincide with each other, then there are infinitely many solutions. This method provides a visual representation of the solutions to the system of equations.

How do you solve a system of linear equations algebraically using substitution or elimination?

To solve a system of linear equations algebraically using substitution, you isolate one variable in one of the equations and substitute it into the other equation. This creates an equation with only one variable, which you then solve to find its value. You then substitute this value back into one of the original equations to find the value of the other variable. In elimination, you manipulate the equations by adding or subtracting them to eliminate one variable, allowing you to solve for the other variable directly. Keep manipulating the equations until you have found the values for both variables, which satisfy all equations in the system.
