What are the coordinates of the vertices?
Answer provided by our tutors
You can fin the vertices by solving the following systems of equations:
y= -3, y=2x+1;
x = 2, y=2x+1;
x = 2, y=-3;
The solution for y= -3, y=2x+1 is the intersection of the two lines represented by the equations and gives the vertex: (-2, -3)

The solution for x= 2, y=2x+1 is the intersection of the two lines represented by the equations and gives the vertex: (2, 5)
