To find the midpoint you divide the sum of the x and y coordinate by 2 because you want to find the middle.
((2+4)/2,(1+-3)/2)
So simplify and get answer
(3,-1)

Answer:
3x+3
Step-by-step explanation:
We can ad up all of those
x+x+6+x-3= so we get 3x+6-3 which is 3x+3
Answer: About 6.71 units
Step-by-step explanation:
You use the distance formula: 
.
Assign the the two points to the variables:
Substitute them in the formula:
And solve it:
A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon's center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).
answer:
(-2,7) is reflected to (-2,-7)
(3,9) is reflected to(-3,9)
(7,2) is reflected to(7,-2)
(-3,-9)is reflected to (-3,9)
