This equation does not have real roots as the discriminant is negative.  d= b^2-4ac= 5^2-4*7=-3it has two immaginary roots. 

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.

Graph a should be your answer
