Answer:
Option (C)
Step-by-step explanation:
If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.
By the property of perpendicular lines,
![m_1\times m_2=-1](https://tex.z-dn.net/?f=m_1%5Ctimes%20m_2%3D-1)
where
is the slope of the line AD and
is the slope of BC.
![m_2=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m_2%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![=\frac{8+2}{3-7}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B8%2B2%7D%7B3-7%7D)
![=-\frac{5}{2}](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B5%7D%7B2%7D)
Now from the given property,
![m_1\times (-\frac{2}{5})=-1](https://tex.z-dn.net/?f=m_1%5Ctimes%20%28-%5Cfrac%7B2%7D%7B5%7D%29%3D-1)
![m_1=\frac{5}{2}](https://tex.z-dn.net/?f=m_1%3D%5Cfrac%7B5%7D%7B2%7D)
Therefore, slope of altitude BC = ![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
Option (C) will be the answer.
Answer:
y=1.3 x - 0.21
Step-by-step explanation:
![y = (slope) \times x + (constant)](https://tex.z-dn.net/?f=y%20%3D%20%28slope%29%20%5Ctimes%20x%20%2B%20%28constant%29)
set (-2.3,-3.2) in above
![- 3.2 = 1.3 \times ( - 2.3) + c](https://tex.z-dn.net/?f=%20-%203.2%20%3D%201.3%20%5Ctimes%20%28%20-%202.3%29%20%2B%20c)
then c=-0.21
