To find the coordinates of point B, we need to reflect point A over point (-1,-5).Step 1: Find the midpoint between point A and point (-1,-5).The midpoint formula is given by:Midpoint = ((x1 + x2)/2, (y1 + y2)/2)Using the midpoint formula, we can find the midpoint between point A and point (-1,-5):Midpoint = ((4 + (-1))/2, (-6 + (-5))/2)Midpoint = (3/2, -11/2)Step 2: Reflect point A over the midpoint.To reflect a point over a midpoint, we need to find the distance between the point and the midpoint, and then move the same distance on the other side of the midpoint.Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)Distance = sqrt((4 - (-1))^2 + ((-6) - (-5))^2)Distance = sqrt(5^2 + (-1)^2)Distance = sqrt(25 + 1)Distance = sqrt(26)Since we are reflecting point A over the midpoint, we need to move the same distance on the other side of the midpoint. Therefore, the coordinates of point B will be:B = (Midpoint_x - Distance, Midpoint_y - Distance)B = (3/2 - sqrt(26)/2, -11/2 - sqrt(26)/2)Therefore, the coordinates of point B are (3/2 - sqrt(26)/2, -11/2 - sqrt(26)/2).
