What is the definition of 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 the first power of an independent variable. It represents a straight line when plotted on a graph, with a constant rate of change or slope.

How do you graph a linear equation?

To graph a linear equation, start by identifying the slope and y-intercept of the equation in the form y = mx + b. Plot the y-intercept on the y-axis and then use the slope to find a second point to draw a straight line through both points to represent the equation graphically.

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, the point where the line intersect the y-axis.

How do you find the slope of a line given two points?

To find the slope of a line given two points (x1, y1) and (x2, y2), you can use the formula: slope = (y2 - y1) / (x2 - x1). Subtract the y-values and divide by the difference in the x-values to determine the slope of the line passing through the two points.

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

The point-slope form of a linear equation is y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line. This form is useful for finding the equation of a line when given a point on the line and its slope.

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

To solve a system of linear equations using substitution, you first isolate one variable in one of the equations. Then, substitute that expression into the other equation to find the value of the other variable. Finally, substitute this value back into one of the original equations to solve for the first variable. This process allows you to find the values of both variables that satisfy both equations in the system.

What is the y-intercept of a linear equation?

The y-intercept of a linear equation is the point where the line intersects the y-axis. It represents the value of y when x equals zero in the equation. This point is significant as it gives the initial value of the equation and helps in understanding the behavior of the line.

How do you solve a linear equation with variables on both sides?

To solve a linear equation with variables on both sides, first simplify the equation by combining like terms on each side. Then, move the variables to one side of the equation by adding or subtracting terms from both sides until one side has only constants and the other side has all the variables. Finally, solve for the variable by performing inverse operations (such as division or multiplication) to isolate the variable on one side of the equation.

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 x and y are variables.

How do you determine if two linear equations are parallel or perpendicular?

Two linear equations are parallel if their slopes are equal, meaning they have the same rate of change. On the other hand, two linear equations are perpendicular if the product of their slopes is equal to -1. In other words, the slopes of perpendicular lines are negative reciprocals of each other, resulting in a right angle between the two lines.
