Question | Answer |
Change | To become difference.For ex temperature rise and fall. prices increase and decrease and so on. in mathematics, quantities that change are called variables |
Coordinate Grid | A graphical representation of pairs of related values that show the relationship between two variables. It relates the independent(shown on the x-axis) and the dependent variable (shown on the y-axis) |
Coordinate 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 of the x- coordinate, and the second number in the value for the y-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 ex, the cost of a long-distance phone call (dependant variable) depends on how long you talk independant variabl |
Equation, formula | A rule containing variables that represents a mathematical relationship. |
Independent variable | One of two variables in a relationship. Its value determines the value of the other variable called the dependent variable. If you organize a bike tour, for ex the number of people who register to go (independant variable) determenies the cost for rentin |
Pattern | A change that occurs in a predictable way. For ex, the squares on a checkerboard form a pattern in which the color of the square of the square alternate between red and black. The sequence in which the numbers increase by the next odd number. That is 4 is |
Range in value | values for variables that makes scene for the data being considered |
Relationship | An association between two or more variables.If one of the variables change, the other variables may also change, and the change may be predictable |
Rule | A summary of a predictable relationship that tells how to find the value of a variable. A rule may be given in words or as and equation. For ex, this rule relates time,rate,and distance: distance is equal to rate times time, or d = rt |
Scale | A labeling scheme used on each used on each of the axes on a coordinate grid. |
Table | a list of values for two or more variables that shows the relationship between them. tables often represent data made from observations, from experiments, or from a series of arithmetic operations. A table may show a pattern of change between two variable |
Variable | A quantity that can change. Letters are often used as symbols to represent variables in rules or equations that describe patterns. |
Stmbolic form | anything written for two or more expressed though the use of symbols. |
x-axis | the number line that is horizontal on a coordinate gird |
y-axis | the number line that is vertical of the coordinate gird |
