constant of variation | the slope, or rate of change, in the equation y=ks, represented by k |
constant rate of change | when the rate of change between any two data points in a linear relationship is the same or constant |
direct variation | a special type of linear equation that describes rate of change/ a relationship such that x increases in value, y increases or decreases at a constant rate |
line of fit | on a scatter plot, a line drawn that is very close to most of the data points/ the line that best fits the data |
linear equation | an equation in which the variables appear in separate terms and neither variable contains an exponent other than 1/ the graph of this is a straight line |
linear relationship | relationships that have straight line graphs |
rate of change | a change in one quantity with respect to another quantity |
slope | the ratio of the rise, or vertical change, to the run, or horizontal change/ describes the steepness of the line |
vertical line test | if any vertical line drawn on the graph of a relation passes through no more than one point on the graph for each value of x in the domain, then the relation is a function |
y-intercept | the y-coordinate of a point where a graph crosses the y-axis |
