Looking at the function it is between the x intercepts
The x intercepts ares -2 and 1
-2 <x<1 is when y >0
We want interval notation
(-2,1)
If shapes are congruent, then they are mathematically equal (same dimensions, angles etc.). So just locate where the angle x is on both triangles, it should have a value on or a calculable value on the other. If you provide us with the actual sheet I could walk you through it.

Answer:
The second one is the right one
You need 2 points in order to draw this first put x=0 and you will find y= - 4 then solve
