Question 185907
<font face="Times New Roman" size="+2">


You should be able to plot your points and draw *[tex \Large L_1]


First calculate the slope of *[tex \Large L_1] using:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ m_1 = \frac{y_1 - y_2}{x_1 - x_2} ]


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


Now use the fact that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  L_1 \parallel L_2 \ \ \Leftrightarrow\ \ m_1 = m_2]


Parallel lines have the same slope.


So *[tex \Large L_2] has the same slope as *[tex \Large L_1] and passes through the point (0,0).
