| Term | Definition |
|---|---|
| Proportional Relationship | A relationship between two equal ratios |
| Constant of Proportionality | The ratio between two directly proportional quantities (Ex. Buying a pack of two for $3, and finding out how much one would cost, which is $1.50. $1.50 and $1.50 are directly proportional) |
| Conversions | A change in the form of measurement, without changing of the amount being measured. |
| The Slope Intercept Form of a Linear Function | When finding a line on a graph by solving the equation "y=mx+b" (m is equal to the slope and b is equal to the y-intercept) The line passes through the origin |
| Nonproprtional Linear Relationships | When solving for a line on a graph (y=mx+b) and b (the y-intercept) is not equal to zero. The line doesn't pass through the origin |
| Negative Slope | A slope where x is negative and y is positive |
| Positive Slope | A slope where x and y are positive |
| Slope and y-intercept | The slope of a line is its steepness, or slant (y=Mx+b) The y-intercept is the point of the y-axis where the line passes through. (y=mx+B) |
| Vertical Line | A line on the graph that goes straight up and down. X doesn't change |
| Horizontal Line | A line of the graph that goes straight across. Y doesn't change |
| Absolute Value Function | A function that contains an algebraic expression within absolute value symbols. |
| Step Function | a function that increases or decreases abruptly from one constant value to another |
| Graphing Equations and Inequalities | Using y=mx+b to find where a line lays on a graph. |
| Sequence | a string of numbers that follow a particular pattern |
| Arithmetic Sequences | A sequence of numbers such that the difference between the consecutive term is constant |
