Question

A figure with vertical line symmetry is placed on the coordinate plane. Given that the points (–8, –4) and (–3, –4) are on the edges of the figure, which of the following points lies on the line of symmetry?. A.(–5.5, –4). B.(–2.5, 0). C.(5.5, 4). D.(11, 8).

Answer 1

A.(–5.5, –4) is the best answer

Answer 2

Based on the description, the edges lying on those coordinates can be considered end points to a line. In this scenario, we can apply the midpoint formula to find the coordinates that lies on the vertical symmetry. 

Midpoint formula: (x1+x2) / 2 for the x coordinate
                             (y1+y2) / 2 for the y coordinate

After calculating this, we obtain (-5.5, -4) as our midpoint. Hence the answer is letter A.
