Unit 9: Coordinates
Term | Definition |
---|---|
additive pattern | a pattern that occurs when a constant non-zero value is added to an input value to determine the output value (y = x + a) |
coordinate plane | a plane spanned by the x-axis and y-axis in which the coordinates of a point are its distances from two intersecting perpendicular axes |
graph | a visual representation of the relationship between data collected |
multiplicative pattern | a pattern that occurs when a constant non-zero value is multiplied by an input value to determine the output value (y = ax) |
numerical pattern | a list of numbers that follow a certain sequence |
ordered pair of numbers | two numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally (x axis) and the second number tells how far to move vertically (y axis) |
quadrant | any of the four areas created by dividing a plane with an x-axis and y-axis on a rectangular coordinate system |
x-axis | the horizontal number line on a rectangular coordinate system |
x-coordiante | the value of the x-axis is used to locate a point on the coordinate graph; it is the first value in an ordered pair |
y-axis | the vertical number line on a rectangular coordinate system |
y-coordinate | the value of the y-axis used to locate a point on the coordinate graph; it is the second value in an ordered pair |
