Answer:

B)  P' (-4, -4) and Q' (-1, -2)

Step-by-step explanation:

From inspection of the graph:

P = (-4, 4)

Q = (-1 ,2)

If the line PQ is reflected across the x-axis, then the x-coordinates of the points do not change, and the y-coordinates of the points become negative.  

Therefore,

P' = (-4, -4)

Q' = (-1, -2)

Reflected over x axis so x co-ordinates remains constant.

The line is present in Quadrant 2 so it will be shifted to quadrant 3.

  • y co-ordinates will be negative.(In Q3 y<0)

So the rule is (x,-y)

The co-ordinates are

  • P(-4,-4)
  • Q(-1,-2)
