| y-axis | the up-and-down axis of a graph |
| x-axis | the left-and-right axis of a graph |
| standard form | ax+by=c |
| slope-intercept form | y=mx+b |
| slope | the steepness of a line on a graph, equal to its vertical change divided by its horizontal change |
| y-intercept | the spot where a graph intersects the y-axis; the point where x=0 |
| x-intercept | The spot where a graph intersects the x-axis; the point where y=0 |
