Equation of a Line
- Equations that Describe a Line
Use the slope formula with points (−1,4)(-1, 4)(−1,4) and (2,−1)(2, -1)(2,−1):
slope=y2−y1x2−x1=−1−42−(−1)=−53=−53\text{slope} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - 4}{2 - (-1)} = \frac{-5}{3} = -\frac{5}{3}slope=x2−x1y2−y1=2−(−1)−1−4=3−5=−35
