Reflect shape a in the line x=-2.

Here's what I get  

Step-by-step explanation:

When you reflect a shape about a line, each point in the image is the same distance from the line of reflection as the corresponding point in the pre-image.  

You may be able to just count these distances on the grid.

However, the rule for reflection about a line x = h is (x,y) ⟶ (2h - x,y}

I will use the rule to calculate the coordinates of the image.

The Figure below shows your shape reflected across the line x = -2.
