the error was that he inputted the coordinates wrong, he should ahve seperated the x ande y values . The correct answer is (5.5, -2)

# data[].attributes.body
What went wrong was they added the set of coordinate together instead of doing X1, X2 and Y1, Y2. Which wasn't the correct formula. The correct answer is 5.5 and -2

# data[].attributes.body
He added x1+y1 and x2+y2 instead of x1+x2 and y1+y2

# data[].attributes.body
It should be -2+13 and you get 11 then 3+-7 equals to -4 now 11/2 is 5.5 and -4/2 is -2.

# data[].attributes.body
In the equation, the problem is supposed to be (x1+x2)+(y1+y2). However, they did it as (x1+y1)+(x2+y2) which is wrong. In this case the answer is (5.5,-2).

# data[].attributes.body
Error: is that -2 and 13 are x so that need be together but they put x one with x two in the same problem so that's incorrectly .

# data[].attributes.body
they didn't add X1 to X2 they added X1 to Y1. The real answer should be. (5.5,-2)     :)

# data[].attributes.body
The error is you're not supposed to add x and y together. The correct answer is, (11/2,-2).

# data[].attributes.body
Instead of adding X two and X one and adding Y two and Y one, he just added. He should have added 13 + -2, and -7 + 3. He would have gotten 11/2, -2. Instead he just added x one and y one then divided, which is wrong.

# data[].attributes.body
the ponts wear addec by both points instead of x1 and x2 being added they added the whole coordinate.( 5.5,2)

# data[].attributes.body
the error was that he was supposed add -2 and 13 and add 3 and -7  and so everything after the is wrong. the correct answer is (5.5,-2)

# data[].attributes.body
The error is that they added the whole coordinates together instead of adding both x's and y's together.

The correct answer is (5.5, -2).

# data[].attributes.body
They put the coordinates in the wrong spots. The correct answer would be (5.5, -2).

# data[].attributes.body
The error is that they didn't use the correct formula. They added x1, x2 and y1, y2. The correct answer is (5.5, 2)

# data[].attributes.body
The error they made was that they did the adding wrong and put the x and y in the wrong place . The answer I got was (11/2), -2

# data[].attributes.body
They didn't set the equation up correctly.

# data[].attributes.body
The error is that they added x1 and y1 together. They also added x2 and y2 together. The correct answer is (5.5,-2)

# data[].attributes.body
They did not set up the equation properly, they added x and y together instead of x and x. THe correct answer is (5.5, and -2

# data[].attributes.body
Instead of x1+x2,vise versa, this person tried to solve by doing x1+y1, the correct answer is (5.5, -2)

# data[].attributes.body
They added up x1 with y1 when its x1 with x2 and y1 with y2
ANS=5.5, -2

# data[].attributes.body
The first equation was incorrect, instead of X+X and Y+Y the equation was setup X+Y and X+Y, which would be the wrong answer but following the correct setup the answer would be (5.5, -2)

# data[].attributes.body
instead of doing x1+ x2/2 and y1 + y2 /2 they did x1+ x2  /2 + x2 + y2 /2
correct asnwe

# data[].attributes.body
First they messed by adding x and y not x1 and x2 or y1 and y2, the correct answer is (5 1/2, -2)

# data[].attributes.body
the 3 and 13 are put in the wrong place.

# data[].attributes.body
the error was they didn't put the formula correct they didn't do X1 + X2 and Y1 + Y2 the correct answer would be

# data[].attributes.body
They didn't do the distance formula properly, the answer would be  5.5,-2  so if they put the x's and y's together they would get a different answer.

# data[].attributes.body
The error is that they did the equation wrong, they did not use the equation properly.  It should be (-2+13),(3+(-7). The correct answer is  (5.5, -2)

# data[].attributes.body
The error in this equation is that instead of adding both x1 and x2, they added x1 and y1. The actual equation should have been [(-2)+1] divided by two, and then add to that [3+ (-7)] divided by two. Lastly you divide both those answers by 2. The actual answer is (5.5,-2
)

# data[].attributes.body
The x and y were not with there other x and y there for the solution is wrong , the correct answer is 5.5 and -2.

# data[].attributes.body
The error made in the problem is the midpoint formula was not used correctly. Instead of using the x and y values as the formula states this particular problems used the coordinates. The correct answer is 5.5 on the x and -2 on the y.

# data[].attributes.body
The error is that they didn't add X1 and X2, they added together X1 and Y1... THe correct answer is
M= (11/2) , -2

# data[].attributes.body
They didn't put apart the numbers into the correct formula where it's x1+x2 and y1+y2 over two instead of x1+y1. The answer( 5.5,2)

# data[].attributes.body
They added x1 and y1 instead of x1 + x2 and y1 + y2 the correct answer would be (5.5, -2)

# data[].attributes.body
Instead of using X1 and X2 and Y1 and Y2, the student used x and y together. The correct coordinates of the midpoint are (5.5, 2).
