arithmetic sequence
a sequence in which the difference between any 2 consecutive terms is the same
best-fit line
A line that is very close to most of the data points in a scatter plot.
boundary
a line that seperates the solutions from the points that are not solutions in the graph of an inequality.
common difference
the difference between any 2 consecutive terms in a sequence.
common ratio
the quotient between any 2 consecutive terms in a geometric sequence.
dependent variable
the variable for the output of a function.
domain
the set of input values in a function.
function
a relation in which each element of an input is paired with exactly one element of the output according to a specified rule.
function table
a table organizing the input, rule, and output of a function.
geometric sequence
a sequence in which the quotient between and 2 consecutive terms is the same (multiplying).
half plane
The region that contains the solutions in the graph of a linear inequality.
independent variable
the variable for the input of a function.
linear function

range
the set of output values in a function.
scatter plot
a graph that shows the relationship between two sets of data
sequence

slope formula
m = (y2 - y1) / (x2 - x1)
slope-intercept form
y=mx+b
substitution

system of equations
a set of 2 or more equations that are considered together.
term
a number in a sequence.
x-intercept
the value of x where the graph crosses the x-axis.
y-intercept
the value of y where the graph crosses the y-axis.
