a #s distance from zero on the number line for example the ?? of 3 is written as |3|

• absolute value
• y-coordinate

a conclusion you reach by inductive reasoning

• conjecture
• y-axis

formed by the intersection of two number lines

• coordinate plane
• x-coordinate

an example that proves the statement is false

• counterexample
• x-axis

to ? a variable expression, you first replace each variable with a number. Then you use order of operations to simplify

• evaluate
• variable expression

making conclusions based on patterns you observe

• inductive reasoning
• variable

whole numbers and their opposites

• integers
• quadrants

#s that are the same distance from zero on a # line but in opposite directions

• opposites
• origin

the order which you perform operations: multiple and divide first then add and subtract

• order of operations
• ordered pair

gives the coordinates and location of a point

• ordered pair
• order of operations
