What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x. A positive slope indicates the line rises, while a negative slope indicates it falls.

Front

How do you graph a linear equation?

Back

To graph a linear equation, identify the y-intercept (b) on the y-axis, use the slope (m) to find another point, and draw a straight line through these points.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or equal to the other.

How do you solve a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side of the inequality sign, similar to solving an equation, and then graph the solution on a number line.

What does it mean for a line to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts, meaning they will never intersect.

Front

What does it mean for a line to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1. This means one slope is the negative reciprocal of the other.
