Cartesian Coordinate System
a coordinate system for which the coordinates of a point are its distances from a set perpendicular lines that intersect at the origin of the system
The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.
The value on the y-axis used to locate a point on the coordinate graph. It is the second value in an ordered pair.
graph of the equation
the line consisting of all points whose coordinates satisfy the equation
linear equation in general form
a x + b y = c,
where a, b and c are constants.
The point which a relation intersects the x- or y-axis
Inequality Property 1
Suppose that a<b and that c is any number. Then a+c<b+c and a-c<b-c. In other words, the same number can be added or subtracted from both sides of the inequality.
Inequality Property 2
2A. If a<b and c is positive, then ac<bc.
2B. If a<b and c is negative, then ac>bc.
Ax+By≤C, Ax+By≥C and A and B are not both 0
the graph of a system of inequalities
point of intersection
can be found by
a curve that shows the relationship between the price of a product and the quantity of the product supplied.
a curve that shows the relationship between the price of a product and the quantity of the product demanded
rise over run
straight Line depreciation
One method of calculating the depreciation is to take equal amounts over the expected lifetime of the asset.
marginal cost of production
Point- Slope formula
The equation of the straight line passing through (x1,Y1) and having slope m is given by y-y1=m(x-x1)
When two lines are perpendicular, their slopes are negative reciprocals of one another. That is, if two lines with slopes m and n are perpendicular to one another, then m=-1/n.
Conversely, if two lines have slopes that are negative reciprocals of one another, they are perpendicular.
Lines with the same slope.
