If you plot the points you will find you have to use the distance formula. Pick out 2 pairs label them (x1,y1) (x2,y2) then plug it into the distance formula. The repeat for the other sides. So you should get (2,5) (4,3) plug into distance formula what is get it distance between those two points, then (4,3) (-2,-1) plug into distance formula to get an answer, lastly (-2,-1) (2,5) plug in. Now you have three answers add all together and here is your perimeter of a triangle.
Answer: (-2,-4)
Step-by-step explanation:
To find the midpoint between two points we need to find the mean average between the x and the y .
Since we know the midpoint will have to represent the missing coordinates by the variables.
Solve for x to find the x coordinate by first multiplying both sides by -4.
-6 + x = -8 Add -6 to both sides
+6 +6
x = -2
The x coordinate of the B is -2 now we need to find the y coordinate.
Multiply both sides by 2
4 + y = 0 Subtract 4 from both sides
-4 -4
y = -4
The y coordinate is -4 so the coordinates will be (-2,-4)
