change | To become different. For example, temperatures rise in the fall, prices increase and decrease and so on. In mathmatics, quanities that change are called variables. |
coordinate graph | a graphical representation of pairs of related numerical values that shows the relationship between two variables. It relates the independent variabe (shown on the x-axis) and the dependent variable (shown on the y-axis). |
coorinate pair | an ordered pair of numbers used to locate a point on a coordinate grid. The first number in a coordinate pair is the value for the x-coordinate, and the second number is the value for the y-coordinate. A coordinate pair for the graph shown above is (0,60) |
dependent variable | one of the two variables in a relationship. Its value depends upon or is determined by the other variable called the independent variable. For example, the cost on how long you talk (independent variable). |
equation,formula | a rule containing variables that represents a mathmatical relationship. An example is the formula for finding the area of a circle:A=JTr2. |
independent variable | one of the two variables in a relationship |
equation,formula | a rule containing variables that represents a mathmatical relationship. An example is the formula for finding the area of a circle:A=JTr2. |
independent variable | one of the two variables in a relationship. Its value determines the value of the other variable called the dependent value. If you organize a bike tour, for example, the number of people who register togo (independent variable). |
pattern | a change that occurs in a predictable way. For example, the squares on a checkerboard form a red and black.The sequence of square number:1,4,9,16.... number.That is, 4 is 3 more than 1,9 is 5 more than 4,16 is 7 more than 9, and so on. |
