Lesson Opener

2-1 The Real Number Line Real Numbers = the set of all positive and negative numbers and zero –The point labeled zero is the ORIGIN –Negative numbers = the points to the left of zero –Positive numbers = the points to the right of zero –Real number line: Plotting points = putting a dot on the number line where the given number would be

Opposites = two points that are the same distance from the origin but on opposite sides –Ex: Opposite of 3 = -3 Opposite of –8 = 8 Absolute value = the distance between the origin and the point representing the real number –Symbol = –Ex: Counterexample = you come up with one example to prove that a statement is false

Practice Graph the numbers on a number line. Then write two inequalities that compare the two numbers. 1.) 3, -5, 0 2.) -0.1, -1.1, -1 3.)

Practice 2 Find the opposites of the number 1.) 3.82.) -163.) 0 4.) ) 6.) Evaluate the expression by finding absolute value

REAL NUMBERS RATIONAL NUMBERS = any # that can be written as a fraction or RATIO INTEGERS = positive and negative whole #s WHOLE #s= only positive

Summary The set of numbers consisting of the positive numbers, the negative numbers, and zero are called ___________ ___________. The point labeled zero on the number line is called the _______________. You can graph or plot points on a ___________ ______________. The distance between the origin and the point representing the real number is called the___________ ___________. Two points that are the same distance from the origin but on different sides are called___________.
