math

Mean

the average of a set of values, calculated by adding all the numbers together and dividing by the count of numbers

Median

the middle value in a sorted list of numbers. If there is an even number of values, the median is the average of the two middle numbers

Mode

the value that occurs most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all

Range

highest value to lowest value (highest - lowest)

y = mx + b

slope intercept form

y- y1 = m(x - x1)

point slope form

Ax + By = C

standard form

rx = A|x-h| + k

absolute value function

rx = A(x - h)² + k

quadratic function

rx = A(x-p)(x-q)

linear (degree) equation

rx = Ax² + bx + c

standard form

rx = A(x-h) + k

vertex form

substitution method

plug in a part of equation into the other equation

elimination method

add in from other equation to cancel a variable
