One line passes through(0,0)  and (1,-2)

Slope is (-2-0)/(1-0) =-2

The equation of this line is y = -2x

The other line passes through (3,0) and (0,-3)

Slope =(-3-0)/(0-3) =1

This passes through (0,-3)

y =x-3

These are the two equations 

Solving -2x=x-3

-3x=-3

x=1

y =1-3=-2

The point is (1,-2)
