The equation of a line that is perpendicular to the given line is y = –4x – 16.
Solution:
The equation of a line given is y = 0.25x – 7
Slope of the given line(
) = 0.25
Let
be the slope of the perpendicular line.
Passes through the point (–6, 8).
<em>If two lines are perpendicular then the product of the slopes equal to –1.</em>
![\Rightarrow m_1 \cdot m_2=-1](https://tex.z-dn.net/?f=%5CRightarrow%20m_1%20%5Ccdot%20m_2%3D-1)
![\Rightarrow 0.25\cdot m_2=-1](https://tex.z-dn.net/?f=%5CRightarrow%200.25%5Ccdot%20m_2%3D-1)
![\Rightarrow m_2=\frac{-1}{0.25}](https://tex.z-dn.net/?f=%5CRightarrow%20m_2%3D%5Cfrac%7B-1%7D%7B0.25%7D)
![\Rightarrow m_2=-4](https://tex.z-dn.net/?f=%5CRightarrow%20m_2%3D-4)
Point-slope intercept formula:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
and ![m=-4](https://tex.z-dn.net/?f=m%3D-4)
Substitute these in the formula, we get
![y-8=-4(x-(-6))](https://tex.z-dn.net/?f=y-8%3D-4%28x-%28-6%29%29)
![y-8=-4(x+6)](https://tex.z-dn.net/?f=y-8%3D-4%28x%2B6%29)
![y-8=-4x-24](https://tex.z-dn.net/?f=y-8%3D-4x-24)
Add 8 on both sides of the equation.
![y-8+8=-4x-24+8](https://tex.z-dn.net/?f=y-8%2B8%3D-4x-24%2B8)
![y=-4x-16](https://tex.z-dn.net/?f=y%3D-4x-16)
Hence the equation of a line that is perpendicular to the given line is
y = –4x – 16

Answer:
9.60 or 9.601 if you want the hundreths place
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
BC bisects <DBE and if AC is a straight line then you have that:
<ABD + <DBC = 180 (straight angle because of line AC)
<ABE + <CBE = 180 ( straight angle because of line AC)
Because BC bisects <DBE => < DBC = <CBE
So <ABD and <ABE must be the same to both sum 180 when added < DBC
