Find the equation of the line that passes through (–3, 2) and the intersection of the lines x–2y=0 and 3x+y+5=0.

I think the intersection point is (-10/7, -5/7), but I'm not exactly sure.

Answer:

is y + x + 1 = 0.

Step-by-step explanation:

The given equations are :  x + 2y = 0 and 3x + y + 5 = 0

Now, finding the intersection point of the above system:

from (1) , x = -2y

put in (2), 3 (-2y) + y + 5 = 0

or, 5y = 5 ,or y = 1

If y = 1, pitting in (1), x = -2

So, the intersection lines  is (-2,1).

the other point on line is (-3,2)
The answer the problem is y+x+1=0
