dependent and independent variables

y axis

The y axis is the vertical number line that, together the x axis , forms the coordinate plane

Data

Data are pieces of information collected by asking questions, measuring, or making observations abot the real world.

coordinate plane

A coordinate plane is formed by a horizontal number line called the x axis and a vertical line called the y axis.

dependent variable

A dependent variable is a variable that is a variable whose value changes in response to another independent variable.

function

A function is a rule for taking each input value and producing exactly one output value.

linear equation

An equation is a linear equation if the graph of all of its solutions is a line

independent variable

An independent variable is a variable whose value determines the value of another (dependent variable)

ordered pair

An ordered pair identifies the location of a point in the coordinate plane. the x coordinate shows a point position left or right of the y axis. the y coordinate shows a point position up or down from the x axis.

origin

The origin is the point of intersection of the x and y axis and y axis on a coordinate plane

x axis

The x axis is the horizontal number line that, together with the y axis, forms the coordinate plane
