Question

Find the midpoint of AB .

A. (3, 1)
B. (1, 1)
C. (10, 4)
D. (4, 4)

I will attach the picture if someone could help me with it! :-)

Answer 1

I think it's (1,1) am I right?

Answer 2

A is (-2,0)
B is (4,2)
Midpoint is (1,1)

Answer 3

(correct)

Answer 4

Thanks :D

Answer 5

midpoint \[=\subset3+1\div2 , 1+1\div2\supset =\subset2,1\supset\]

Answer 6

A (-2,0)
B (4,2)
midpoint is (mean of x's, mean of y's)

so x = (-2+4)/2
y = (0 + 2)/2

so (1,1)

Answer 7

Okay, thanks guys!!!! Would anyone be willing to help me with a few more questions?

Answer 8

Well, the mid-point M(X,Y) of the line joining two points, say A(x,x') and B(y,y') is:

\[(X,Y) = (\frac {x+x'} 2 , \frac{y+y'}{2}) \]

Answer 9

Yes, post as new questions, peetalove.

Answer 10

Here is the next one if someone would like to help me through it.

2.) Ingrid is making a quilt using squares that measure 5 in. on a side. What is the length of a diagonal of one of the quilt squares? Round to the nearest tenth.

A. 8.7 in.
B. 7.1 in.
C. 3.5 in.
D. 14.2 in.

Answer 11

I am thinking C... But I'm not sure

Answer 12

Use pythagoras

a^2 + b^2 = c^2
5^2 + 5^2 = c^2
50 = c^2
c = √50
