Finding Intercepts
Y-intercept Methods
| Method | How To | Example |
|---|---|---|
| From equation | Set x = 0 | y = 3x + 5 → y = 5 |
| From y = mx + c | Read the c value | y = 2x - 3 → c = -3 |
| From graph | Find where line crosses y-axis | Read coordinates |
X-intercept Methods
| Method | How To | Example |
|---|---|---|
| From equation | Set y = 0, solve for x | 0 = 3x + 5 → x = -5/3 |
| From graph | Find where line crosses x-axis | Read coordinates |
