Term | Definition |
---|---|
Radical symbol | The symbol used to represent the non negative square root of a number. |
Slope | A measure of the steepness of a line on a graph. |
coefficient | The number that is multiplied by the variable in an algebraic expression. |
cubed root | One of the three equal factors (multiplication) of a number. It is the side of a cube. |
Function | An input-output relationship that has exactly one output (y-value) for each input (x-value). |
intercepts | Points where a line crosses the x-axis and y-axis. |
irrational number | A number that can not be expressed as a ratio of two integers or as a repeating or terminal decimal. |
Line of best fit | A straight line that comes closest to the points on a scatter plot having an equal number of points above and below the line. |
linear equation | An equation that makes a straight line when it is graphed. |
non-linear function | A function (equation) whose graph is not a straight line. |
outlier | A value much greater or much less than the others in a set of data. |
radical symbol | The symbol used to represent the non negative square root of a number. |
rational number | A number that can be expressed as a ratio (fraction) of two integers. |
scatter plot | A graph with points plotted to show a possible relationship between two sets of data. |
scientific notation | A method of writing very large or very small numbers using powers of 10. |
slope intercept form | A linear equation written in the form y=mx+b (m represents slope and b represents the y-intercept). |
square root | One of the two equal factors (multiplication) of a number. It is the side of a square. |
Domain | The set of x-values that give rise to real y-values. |
equations | mathematical sentences built from expressions using one or more equal signs. |
evaluate | To find the value of an expression. |
exponent | Indicates how many times the base is to be used as a factor. |
formula | An expression used to calculate a desired result. |
order of operations | PEMDAS (parentheses, exponents, multiply/divide, add/subtract) |
range | The set of y-values of a function or relation |
slope | A measure of the steepness of a line on a graph |
variable | A symbol for an unknown number usually expressed as a letter |
y-intercept | A point which a graph intersects the y-axis |
