| Question |
Answer |
| algebra |
a branch of mathematics dealing with symbols |
| algebra expression |
an expression that contains sums and/or products of variables and numbers |
| coordinate plane |
another name for coordinate system |
| coordinate system |
a coordinate system is formed by the intersection of two number lines that meet at right angles at their zero points, also called a coordinate plane |
| counterexample |
an example that shows conjecture is not true |
| deductive reasoning |
the process of using facts, properties, or rules to justify reasoning or reach valid conclusions |
| defining a variable |
choosing a variable and a quantity for the variable to represent in an equation |
| domain |
the domain of relation is the set of all x-coordinates from each pair |
| equation |
a mathematical sentence that contains an equal sign (=) |
| evaluate |
find the numerical value of an expression |
| function |
a function is a special relation in which each element of the domain is paired with exactly one element in the range |
| function rule |
the operation performed on the input of a function |
| function table |
a table organizing the input, rule, and output |
| graph |
a dot at the point that corresponds to an ordered pair on a coordinate plane |
| numerical expression |
a combination of numbers and operations such as addition, substraction, multiplication, and division |
| order of operations |
the rules to follow when more than one operations is used in an expression. Think PEMDAS ***MD left to right and ***AS left to right |
| ordered pair |
a pair of numbersused to locate any point on a coordinate plane |
| origin |
the point at which the number lines intersect in a coordinate system |
| properties |
statements that are true for any numbers |
| range |
the range of a relation is the set of all y-coordinates from each ordered pair |
| relation |
a set of ordered pairs |
| scatter plot |
a graph that shows the relationship between two set of data |
| simplify |
to write an expression in a simpler form |
| variable |
a placeholder for any value |
| x-axis |
the horizontal number line which helps to form the coordinate system |
| x-coordinate |
the first number of an ordered pair |
| y-axis |
the vertical number line wich helps to form the coordinate of a point where a graph crosses the y-axis |
| y-coordinate |
the second number of an ordered pair. |
