Essential Facts About Straight Line Graphs
- Linear relationship: One variable changes at a constant rate with respect to another
- Straight line: All points lie on the same straight line
- General form: y = mx + c (where m = gradient, c = y-intercept)
- Gradient: How steep the line is (rise over run)
- Y-intercept: Where the line crosses the y-axis
