P.1- Graphical Representation of Data
Quadrants
Distance formula:
Find the distance between points (6,-3),
(6,5)
Midpoint Formula
Standard for of the equation of a circle
P.2- Graphs of Equations
Sketching a graph by point plotting
Solve the equation for y using the variables such
as -1,0,1,2,3 for x.
To graph, plot the points (x,y) and connect
Tip: when graphing with a calculator, make
sure to adjust the graphing window in order to get the full geometric
perspective
P.3- Lines in the Plane
Slope is change in y over change in x
Point- Slope Formula
Slope-Intercept
Two distinct nonvertical lines if an only if
their slopes are equal
Two nonvertical lines are perpendicular if
and only if their slopes are negative reciprocals of each other:
P.4- Solving Equations Algebraically and
Graphically
When dealing with absolute value equations, always isolate the
absolute value first. Break into two equations, one with positive values inside
the absolute value symbol and one with negative. Solve both equations and
check.
Solving an equation of Quadratic Type
Solving an equation involving a Radical
Solving an equation by Factoring
