Real Numbers Natural numbers: (0,∞) Whole Numbers: [0,∞) Integers: (-∞,∞) Rational Numbers: dec representation repeats or terminates Irrational Numbers: dec representation doesn’t terminate or repeat ex: pi
The Distributive Property The Distributive Property: Where a , b and c are any real numbers. First, let me remind you what it means when two letters are right next to each other in math. This is an Algebra thing!

2.1 FUNCTIONS AND THEIR GRAPHS Linear Equations in Two Variables Using Slope The simplest mathematical model for relating two variables is the linear equation in two variables y = mx + b . The equation is called linear because its graph is a line. (In mathematics, the term line means straight line.) By letting x = 0, you obtain y = m(0) + b substitute 0 for x. = b So the line crosses the y- axis at y = b . In other words, the y-intercept is (0,b). The steepness or slope of the line is m. y = mx + b slope y-intercept The slope of a nonvertical line is the number of units the line rises (or falls) vertically for each unit of horizontal change from left to right. A linear equation that is written in the form y = mx + b is said to be written in slope-intercept form. The Slope-Intercept Form of the Equation of a Line
