Answer:

The equation of line passing through origin and parallel to first line is  5 X + 3 Y = 0

Step-by-step explanation:

Given as :

The points through which line AB passes are A ( - 3 , 0)  and  B ( -6 , 5 )

SO the slope line AB = (m1) = [tex]\frac{y2 -y1}{x2 - x1}[/tex]

Or,                                  (m1) = [tex]\frac{5 - 0}{-6+3}[/tex]

Or,                                  (m1) =   [tex]\frac{5}{-3}[/tex]

Now Another line passes through origin ( 0 , 0)

And another line is parallel to first line AB ,  so, (m2) = (m1 ) = [tex]\frac{5}{-3}[/tex]

Now equation of another line passing through origin and slop (m2) is :

Or, Y - 0 = [tex]\frac{5}{-3}[/tex] (X -0)

Or  - 3 Y = 5 X

∴      Y =   - [tex]\frac{5}{3}[/tex] X

Hence The equation of line passing through origin and parallel to first line is  5 X + 3 Y = 0   Answer
