IfA=(-2,-4) and B=(-8,4), what is the length of AB?
lisabon 2012 [21]

Answer:

<h2>10 units </h2>

solution,

A(-2,-4)--->(X1,y1)

B(-8,4)----->(x2,y2)

now,

ab =  \sqrt{(x2 - x1) ^{2}  +  {(y2 - y1)}^{2} }  \\  \:  \:  \:  \:  =  \sqrt{ (- 8 - ( - 2)) ^{2} + (4 - ( - 4))  ^{2} }  \\  \:  \:  \:  =  \sqrt{( - 8 + 2) ^{2} +  {(4 + 4)}^{2}  }  \\  \:  \:  \:  =  \sqrt{( - 6) ^{2} +  {(8)}^{2}  }  \\  \:  \:  =   \sqrt{36 + 64}  \\  \:  \:  \:  =  \sqrt{100}  \\  \:  \:  \:  =  \sqrt{ {(10)}^{2} }  \\  \:  \:  \:  \:  = 10 \: units

Hope this helps..

Please help! (I'll give brainliest to the first right answer.)
a_sh-v [17]

Answer:

1. 2,3; -2, 3

2. Both points share common values, but their absolute values for the x-value vary.

3. 2,3; 2, -3

4. Both points share common values, but their absolute values for the y-value vary.  

Step-by-step explanation:

For 1, the answer is thus:

-On the graph, the original point is 2, 3.

-A reflection over the y-axis changes the x-value, so it would be -2,3.

Similar for the next chart:

-The initial point is 2,3.

-A reflection over the x-axis changes the y-value, so the reflected point would be 2, -3.

The explanation is:

Both points have similar values except with differences in the absolute value.

Hope this helps you.
