|
Degree of a Polynomial |
The sum of the exponents of the variables in the monomial Degree of 3x^2y^2 + 4xy^5 - 12x^3y^2 = 6 |
|
|
The Absolute Value |
The absolute value of x is the distance from 0 to x on a number line. |-8| = 8 |3| = 3 |
|
|
Like Terms |
Terms with the same variables raised to the same exponets 3a^2b^2 and 7a^2b^2 |
|
|
Slope |
A measure of the steepness of a line. If (x,y) and (x2,y2) are any two points on a graph, the slope of the line, known as m, is represented by the equation m = y2 - y1 / x2 - x1 |
|
|
Whole number |
The set of zero and all natural numbers {0,1,2,3...} |
|
|
Discrete graph |
A graph made up of unconnected points |
|
|
Slope-intercept form |
Standard form of a linear equation is y = mx + b, where m is the slope of the equation and b is the y-intercept. |
|
|
Direct Variation |
A linear relationship between two variables, x and y, can be written in the form of y = kx, where k is a non-zero constant |
|
|
Inverse Operations |
Operations that undo each other. + -; * / |
|
|
Opposites |
The opposite of a natural number a is the number that is the same distance from zero as -a on the opposite side of the graph. The sum of the numbers is 0. |
|
|
Function |
A relation in which every input is paired with exactly one output.
x y - - 0 0 1 2 2 4 3 6 |
|
|
Reciprocal
|
For all real numbers, except 0, the reciprocal of a is 1/a. The product if the number and its reciprocal is 1. number reciprocal ------------------------------ 2 1/2 1 1 -1 1 0 undefined |
|
|
Coefficient |
A number multiplied by a variable. In the coefficient 2x + 3y, 2 is the coefficient of x and 3 is the coefficient of y. |
|
|
Independent Variable |
The input of a function; a variable whose value determines the value of the output, or dependent variable. {x + y = 7} {x - y = 1} Solution: (4,3) |
|
|
Constant |
A value that does not change (3, 0, π) |
|
|
Leading Coefficient |
The coefficient of the first term of a polynomial in standard form 6x - 7x - 5; -1x - 5; Leading Coefficient: -1x |
|
|
Consistent Systems |
A system of equations or inequalities that has at least one solution x + y = 6 x - y = 4 Solution: (5,1) |
|
|
Inconsistent systems |
A system of equations or inequalities that has no solutions {x + y = 0} |
|
|
Integers |
A member of the set of whole numbers and their opposites {...-3,-2,-1,0,1,2,3...} |
|
|
Perpendicular Lines |
Lines that intersect at 90° angles ^ | <--------------------------> | | V |
|
|
Natural Numbers |
All counting numbers {1,2,3,4...} |
|
|
Dependent Variable |
The output of a function; a variable whose value depends on the value of the input, or independent variable. For y = 2x + 1 input = x; output = y |
|
|
Parallel Lines |
Lines in the same plane that do not intersect <----------------------> <----------------------> |
|
|
Set of whole numbers |
{0,1,2,3...} |
