- origin
- the point where the x-axis and the y-axis intersect in a coordinate plane
- y-coordinate
- the second number in an ordered pair that represents a point; it indicates the distance fro the x-axis
- x-axis
- the horizontal number line in a Cartesian coordinate system
- estimation
- the process of finding the approximate value of an expression, often done by rounding
- Cartesian coordinate system
- a method of representing the location of a point using an ordered pair of real numbers of the form (x,y)
- one-step equation
- an equation that requires only one step to solve
- y-axis
- the vertical number line in a Cartesian coordinate system
- equivalent equations
- two equations that have the same solution, or solutions
- quotient
- the number that results from the division of one number by another
- inverse operations
- operations that undo each other
- two-step equation
- an equation that requires two steps to solve
- percent equation
- an equation in the form a= (p/100)b, where p is the percent and the numbers being compared are a and b.
- integers
- all whole numbers and their additive inverses, ex: -4,-3,-2,-1,0,1,2,3,4,...
- x-coordinate
- the first number in the ordered pair which represents a point; it indicates the distance from the y-axis
- ordered pair
- a pair of numbers in the form (x,y) that represents a unique position in a coordinate plane
- coordinate plane
- the plane formed by the intersection of a horizontal real-number line and a vertical real number line
- number line
- a line on which a unique point is assigned to every real number
- commission
- a fee or a percent of sales that is paid to a sales representative or an agent for services rendered
