Answer:

  no real solutions

  complex solutions: x = 0.5±i√10.75, y = -2.5±i·3√10.75

Step-by-step explanation:

The graph shows the line and parabola do not intersect, so there are no real solutions to this system of equations.

__

However, the complex x-solutions can be determined from the graph to be ...

  x = 0.5 ±i√10.75

The corresponding y-values can be found from the equation

  y = 3x -4 = 3(0.5 ±i√10.75) -4

  y = -2.5 ± i·3√10.75
