variable
A quantity that can change. They are normally represented as letters.
average speed
rate of distance/time
independent variable
One of two variables in a relationship. This variable determines the value of the other variable.
dependent variable
One of two variables in a relationship. Its value depends on or is determined by the other variable.
income
The amount of money taken in.
Profit
The amount of which income is greater than expenses.
expression
A mathematical phrase containing numbers, variables, and operation symbols.
equation
A rule containing variables that represents a mathematical relationship.
coefficient
The numerical factor in any term of an expression.
rate of change
the amount of change in the dependent variable produced by a given change in the independent variable.
equivalent expressions
Two expressions give the same results for every value of the variable.
terms
A variable, number, or the product of a number and a variable.
solving an equations
Finding the value or values of the variables to make an equation true.
solution of an equation
the value or values of the variables that make an equation true.
coordinate graph
A graphical representation of pairs of related numerical values that shows the relationship between the two variables. It relates the independent variable (x-axis) and the dependent variable (y-axis)
coordinate pair
An ordered pair of numbers used to locate a point on a coordinate grid. The first number in the coordinate pair is the value for the x-coordinate and the second number in the coordinate pair is the value for the y-coordinate.
relationship
An association between two or more variables. If one of the variables changes, the other variable may also change, and the change may be predictable.
table
A list of values for two or more variables that shows the relationship between them.
x-axis
The number line that is horizontal on a coordinate grid.
y-axis
The number line that is vertical on a coordinate grid.
