- point slope form
- y - y = m (x - x)
- slope
- number of units the line rises or falls vertically for each unti of horiontal change from left to right
- graph of a function
- collection of orderd pairs such that x is in the domain of f
- x coordinate
- represents the directed distance from the yaxis to the point
- linear equation in two variables
- y =mx + b
- linear interpolation
- when the estimated point lies between two given points
- ordered pair
- (x,y) called coordinates of the point
- implied domain
- the set of all real numbers for which the expression is defined
- domain
- set of inputs
- distance formula
- the distance between two points
- slope intercept form
- y = mx + b
- parallel
- it their slopes are equal
- zeros
- of x are the x values for whcih y = 0
- relative minimum
- point when the graph goes form decreasing to increasing

- slope
- point plotting method
- basic technique used for sketching graphs
- increasing
- y1 < y2
- piecewise function
- a function defined by two or more equations over a specified domain
- graph of an equation
- is the points that are solutions of the equation
- function
- relation that assigns to each element x in the set A exactly one element in the set B
- linear extrapolation
- extrapolated point does not lie between the given points
- decreasing
- y1 > y2
- perpendicular
- if their slopes are negative reciprocals of each other
- y axis
- the vertical real number line
- vertical line test
- a set of points in a coordinate plane is the graph of y as a function of x is and only if no vertical line intersects the graph at more than one point
- origin symmetry
- (x, y) and (-x, -y)
- solution
- an ordered pair (a,b) when a is substituted for x and b is substiuted for y
- y coordinate
- represents the dircted distance from the xaxis to the point
- midpoint formula
- the midpoint of the line segment joining the points
- secant line
- line through th two points
- quadrants
- four parts of the plane

- y axis symmetry
- (x y) and (-x, y)
- range
- set of outputs
- x axis symmetry
- (x,y) and (x, -y)
- constant
- y1 = y2
- intercepts
- the points at which the graph intersects or touches the x or y axis
- origin
- the point of intersection of these two axes
- relative maximum
- point when the graph goes from increasing to decreasing
- x axis
- the horizontal real number line
- even
- symmetric to y-axis f(-x) = f(x)
