Answer:
B(-2,-6)
Step-by-step explanation:
The midpoint of AB is M, then A(8,4), M(3,-1)
So we can find:
![x_{B} =2x_{M} -x_{A}= 2*3-8= -2\\y_{B}= 2y_{M} -y_{A} = 2*(-1)- 4= -6\\](https://tex.z-dn.net/?f=x_%7BB%7D%20%3D2x_%7BM%7D%20-x_%7BA%7D%3D%202%2A3-8%3D%20-2%5C%5Cy_%7BB%7D%3D%202y_%7BM%7D%20-y_%7BA%7D%20%20%3D%202%2A%28-1%29-%204%3D%20-6%5C%5C)
then B(-2,-6), hope that useful.
Answer:
The slope of the green line is 3.
Step-by-step explanation:
<em><u>Definition: </u></em>If the two lines are said to be perpendicular, than the multiplication of their slope is -1.
In other words, the slope of the perpendicular line is the negative reciprocal of the given slope of the line.
Here we are slope of the red line, which is -1/3
Let's take it as "m1"
Let's take "m2" the slope of the green line.
By the above definition,
![m_1 *m_2 = -1](https://tex.z-dn.net/?f=m_1%20%2Am_2%20%3D%20-1)
Given: ![m_1 = -\frac{1}{3}](https://tex.z-dn.net/?f=m_1%20%3D%20-%5Cfrac%7B1%7D%7B3%7D)
Now plug m1 value in the above statement, we get
![-\frac{1}{3} *m_2 = -1](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B3%7D%20%2Am_2%20%3D%20-1)
Multiply both sides by reciprocal of -1/3. The reciprocal of -1/3 = -3
![-3*-\frac{1}{3} *m_2 = -3*-1](https://tex.z-dn.net/?f=-3%2A-%5Cfrac%7B1%7D%7B3%7D%20%2Am_2%20%3D%20-3%2A-1)
![m_2 = 3](https://tex.z-dn.net/?f=m_2%20%3D%203)
Therefore, the slope of the green line is 3.
