What is the equation of a line in slope-intercept form?

The equation of a line in slope-intercept form is y = mx + b, where m represents the slope of the line and b represents the y-intercept, or the point where the line intersects the y-axis.

How do you solve a simple one-step equation?

To solve a simple one-step equation, you need to isolate the variable by performing the inverse operation of what is being done to the variable. For example, if the equation is 4x = 20, you would divide both sides by 4 to find that x = 5. Always remember to perform the same operation on both sides of the equation to maintain equality.

What is the process for solving a two-step equation?

To solve a two-step equation, you first isolate the variable by undoing the operations in reverse order of operations. Start by using inverse operations to get rid of any addition or subtraction present, then use inverse operations to eliminate any multiplication or division. Perform the same operation on both sides of the equation to maintain its balance. Finally, solve for the variable by performing any necessary calculations. Check your answer by substituting it back into the original equation to ensure it satisfies the equality.

How do you solve an equation with variables on both sides?

To solve an equation with variables on both sides, first simplify both sides by combining like terms. Then move all the terms containing variables to one side by either adding or subtracting them from both sides. After that, simplify the equation again to isolate the variable on one side. Finally, solve for the variable by performing any necessary operations to find the value that satisfies the equation.

What is the quadratic formula used for?

The quadratic formula is used to solve quadratic equations of the form ax^2 + bx + c = 0 by providing the values of x that satisfy the equation. By plugging the coefficients a, b, and c into the formula, one can find the roots or solutions of the quadratic equation, which are the values of x where the equation equals zero.

How do you solve a system of equations using substitution?

To solve a system of equations using substitution, you start by isolating one variable in one of the equations and then substitute that expression into the other equation. This allows you to find the value of the variable that was substituted. After finding the value of one variable, you can back-substitute this value into one of the original equations to solve for the other variable. Repeat this process until you find the values of all variables in the system of equations.

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

A linear equation is a mathematical statement that shows equality between two expressions that are linear in nature, while a linear inequality is a mathematical statement that shows a relationship between two expressions that are linear in nature but with the addition of an inequality symbol (<, ?, >, ?). Linear equations aim to find a specific value that satisfies the equation, whereas linear inequalities aim to find a range of values that satisfy the inequality.

How do you graph a linear equation?

To graph a linear equation, you first need to determine the slope and y-intercept of the equation in the form y = mx + b. The slope (m) tells you how the line slants, and the y-intercept (b) is the point where the line crosses the y-axis. Plot the y-intercept on the y-axis, then use the slope to find additional points by moving up or down based on the rise over run ratio. Connect the points with a straight line to complete the graph of the linear equation.

What is the formula for finding the slope of a line?

The formula for finding the slope of a line is given by the change in the y-coordinates divided by the change in the x-coordinates between two points on the line. This is represented as (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

How do you solve for a specific variable in a formula or equation?

To solve for a specific variable in a formula or equation, isolate the variable by performing inverse operations. This involves rearranging the equation by adding, subtracting, multiplying, or dividing to get the variable on one side and constants on the other. By following the order of operations and simplifying as needed, you can determine the value of the variable you are solving for.
