We are given a location of point Z as :
                  Z(-3,4)
Also, we have to first translate this point by using the rule:
          (x,y) → (x+2,y-1)
This means that the point Z is translated to:
    Z(-3,4)→ Z'(-3+2,4-1)=Z'(-1,3)
    i.e.  Z(-3,4) → Z' (-1,3)
Now again this transformed point is reflected across the x-axis by the rule:
        (x,y) → (x,-y)
Hence, the transformed point will be:
        Z'(-1,3) → Z''(-1,-3)
         Hence, we get that:
            Z(-3,4) → Z''(-1,-3)
