First we can se the points that each line passes, and those are:

(-1, 5) & (0, 2)

(-5, -2) & (0, -4)

From this, we calculate each function, that is:

*Line 1:


m_1=(2-5)/(0-(-1))\Rightarrow m_1=-3

And we calculate the first function:


y-2=-3(x-0)\Rightarrow y=-3x+2

*Line 2:


m_2=(-4-(-2))/(0-(-5))\Rightarrow m_2=-(2)/(5)

And we calculate the second function:


y+4=-(2)/(5)(x-0)\Rightarrow y=-(2)/(5)x-4

So the system is:
