SOLUTIONS
binomial - -a polynomial with two terms
constant - -a value that does not change
factor - -a number or expression that is multiplied by another number or
expression to get a product
monomial - -a number or a product of numbers and variables with whole-number
exponents, or a polynomial with one term
polynomial - -a monomial or a sum or difference of monomials
consistent system - -a system of equations or inequalities that has at least one
solution
dependent system - -a system of equations that has infinitely many solutions
elimination method - -a method used to solve systems of equations in which one
variable is eliminated by adding or subtracting two equations of the system
inconsistent system - -a system of equations or inequalities that has no solution
independent system - -a system of equations that has exactly one solution
, substitution method - -A method used to solve systems of equations by solving an
equation for one variable and substituting the resulting expression into the other
equation(s)
system of linear equations - -a system of equations in which all of the equations
are linear
correlation - -a measure of the strength an direction of the relationship between
two variables or data sets
correlation coefficient - -a number r greater than or equal to -1 and less than or
equal to 1, that describes how closely the points in a scatter plot cluster around the line
of best fit.
linear regression - -a statistical method used to fit a linear model to a given data
set
residual - -the signed vertical distance between a data point and a line of fit
X-Intercept - -The x-coordinate(s) of the point(s) where a graph intersects the x-
axis.
Y-Intercept - -The y-coordinate(s) of the point(s) where a graph intersects the y-
axis.
Linear Function - -A function that can be written in the form y=mx+b, where x is
the independent variable and m and b are real numbers. Its graph is a line.
