1. Key Characteristics of a linear graph: The key characteristics of a linear graph are the slope and the y-intercept. The slope represents the steepness of the line, while the y-intercept represents the point where the line intersects the y-axis. The slope is usually denoted by the letter "m," and the y-intercept is denoted by the letter "b." For example, in the equation y = mx + b, m would represent the slope and b would represent the y-intercept.
2. Inequality Notation: Inequality notation is a way to represent relationships between numbers using symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to). It is commonly used to express that one quantity is smaller or larger than another. For example, the inequality notation 4x + 3 > 7 means that 4 times x plus 3 is greater than 7.
3. Interval Notation: Interval notation is a way to represent a range of numbers using brackets and parentheses. It is commonly used in mathematics to express the set of all real numbers between two specified values. For example, the interval notation (2, 5) represents all the real numbers greater than 2 but less than 5. The parentheses indicate that the endpoints, 2 and 5, are not included in the interval.
