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
x-coordinate
The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.
y-coordinate
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.
standard form
y=mx+b
intercepts
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.
Linear inequalities
Ax+By≤C, Ax+By≥C and A and B are not both 0
feasible set
the graph of a system of inequalities
point of intersection
can be found by
mx+b=y=mx+b
supply curve
a curve that shows the relationship between the price of a product and the quantity of the product supplied.
demand curve
a curve that shows the relationship between the price of a product and the quantity of the product demanded
slope
rise over run
(y2-y1)/(x2-x1)
straight Line depreciation
One method of calculating the depreciation is to take equal amounts over the expected lifetime of the asset.
fixed cost
y intercept
marginal cost of production
the slope
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)
Perpendicular Property
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.
Parallel Property
Lines with the same slope.
annual deduction
yearly depreciation
Salvage Value
What an item's value is after it has surpassed it's expected life span
