inconsistent system
a system of linear equations with no solutions, the graphs are parallel

relationship between data sets
a common multiple of the denominators of two or more fractions
step function

f(x) = |x - h| + k, where the vertex is located at the point (h, k)
arithmetic sequence
a sequence whose consecutive terms have a common difference
a fraction in which the greatest common factor of the numerator and denominator is one; there are no numbers the numerator and denominator can be divided by evenly
an equation in the form y - y₁ = m(x - x₁) where (x₁, y₁) are the coordinates of a point on the line and m is the slope of the line
add the numbers and divide by number of values in the set, also known as the average
solution of a linear inequality
any ordered pair that makes the inequality true
one of a pair of numbers whose product is 1, also known as the multiplicative inverse, sometimes called the "flip of a number", used when dividing fractions

a line that closely approximates a set of data, also called a trend line
graph of a linear inequality
shows all the solutions of the inequality on the coordinate plane using a solid or dashed line and shading
