Question 224242
<font face="Garamond" size="+2">


First use the slope formula to calculate the slope of the segment with endpoints (2,0) and (0,-2):



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ m = \frac{y_1 - y_2}{x_1 - x_2} ]


where *[tex \Large \left(x_1,y_1\right)] and *[tex \Large \left(x_2,y_2\right)] are the coordinates of the endpoints.


Then use the fact that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  L_1 \perp L_2 \ \ \Leftrightarrow\ \ m_1 = -\frac{1}{m_2} \text{ and } m_1, m_2 \neq 0]


to calculate the slope of any perpendicular to the given line segment by taking the negative reciprocal of the slope calculated above.
