: A presentation of a real number by points on the real number line using an order pair.Order pairs:
A point ( x , y ) on the coordinate plane. Eg. (-3,5), (0,5)…Origin:
The intersection of x-axis and y-axis Relations:
Sets of ordered pairs ( x , y )Domain:
All the x-values on the coordinate systemRange:
All the y-values on the coordinate systemIndependent Variable:
The "x" values, which are also known as the inputs when solving for a solution.Dependent Variable:
The "y" values, which are also known as the outputs when solving for a solution.
