Integers

• Integers represent any positive or negative whole number, and includes zero

• Integers can be place on a horizontal or vertical number line

• On a horizontal line, negative numbers go to the left of zero, and positive numbers go to the right

• On a vertical line, negative numbers go below zero, and positive numbers go above

• -7

• -2

• 0

• -10

Absolute Value

• The absolute value of a number represents the number's distance from zero on a number line

• Absolute value is always positive

• You can find the absolute value by keeping the number without the sign

• |-3| = 3

• |+18| = 18

• |1,566| = 1,566

Multiple Choice

What's a way to define absolute value?

• The value of a number

• The opposite of a number

• The distance of a number from zero

• The multiplicative inverse of a number

Multiple Choice

Is absolute value always positive?

• yes

• no

Multiple Choice

|-20|

• 20

• -20

Multiple Choice

Compare |-5| to the |-10|

• |-5| > |-10|

• |-5| = |-10|

• |-5| < |-10|

Multiple Choice

Which has the same absolute value as -55?

• 0

• -1

• 1

• 55

Opposites

• Integers that are opposites are on the opposite side of zero on a number line

• Opposites have different signs

• Opposites have the same absolute value

• -8 and + 8 are opposites

• 150 and -150 are opposites

Coordinate Plane

• A coordinate plane is created by intersecting a horizontal number line (X-Axis) and a vertical number line (Y-Axis)

• A coordinate has 4 quadrants

• Quadrant 1 has a positive x + positive y

• Quadrant 2 has a negative x + positive y

• Quadrant 3 has a negative x + negative y

• Quadrant 4 has a positive x + negative y

Ordered Pairs

• An ordered pair shows where to plot a point within a coordinate plane

• Ordered pairs are always written in the following form, (x, y)

• First Value = x, plot left if negative and right if positive

• Second Value = y, plot down if negative and up if positive

Multiple Choice

• up and down

• left to right

Multiple Choice

The x axis stretches
