| bivariate data | a set of data that is made of two paired variables |
| linear equation | an equation whose solutions form a straight line on a coordinate e plane |
| nonlinear relationship | a relationship between two variables in which the data do not increase or decrease together at the same rate |
| ordered pair | a pair of numbers that can be used to locate a point on a coordinate plane |
| proportional relationship | a relationship between two quantities in which of the ratio of one quantity to the other quantity is constant |
| slope | a measure of the steepness of a line on a graph: the rise divided by the run |
| x coordinate | the first number in an ordered pair: it tells the distance to move right or left from the origin (0,0) |
| y coordinate | the second number in an ordered pair: it tells the distance to move up or down from the origin (0,0) |
| y intercept | the y coordinate of the point where the graph of a line crosses the y axis |
