Define a variable in the context of algebra. Why is it important?

Back

A variable is a symbol (often a letter) that represents an unknown value in an equation or expression. It is important because it allows us to formulate general rules and solve problems involving unknown quantities.

What is the difference between an equation and an expression?

Back

An equation is a mathematical statement that asserts the equality of two expressions, while an expression is a combination of numbers, variables, and operators without an equality sign.

How do you solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations, ensuring to maintain the equality.

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it represents how much the dependent variable changes for a unit change in the independent variable.

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect, meaning they have no points in common.

What is the formula for the slope of a line given two points?

Back

The slope (m) of a line through two points (x1, y1) and (x2, y2) is calculated as m = (y2 - y1) / (x2 - x1).

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

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

What is the process for graphing a linear equation?

Back

To graph a linear equation, identify the y-intercept, use the slope to find another point, and draw a line through these points.
