Multiply base x height then divide by 2 if finding surface are if finding volume multiple base x height x width and divide by 3
Given:
Line a is perpendicular to line b
.
Line a passes through the points (1,-8) and (9,-12)
.
Line b passes through the point (-8, -16).
To find:
The equation of b.
Solution:
Line a passes through the points (1,-8) and (9,-12)
. So, slope of line a is
Product of slopes of two perpendicular lines is -1.
![m_a\times a_b=-1](https://tex.z-dn.net/?f=m_a%5Ctimes%20a_b%3D-1)
![-\dfrac{1}{2}\times a_b=-1](https://tex.z-dn.net/?f=-%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20a_b%3D-1)
![b=2](https://tex.z-dn.net/?f=b%3D2)
Slope of line b is 2.
If a line passing through a point
with slope m, then equation of line is
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Line b passing through (-8,-16) with slope 2. So, equation of line b is
![y-(-16)=2(x-(-8))](https://tex.z-dn.net/?f=y-%28-16%29%3D2%28x-%28-8%29%29)
![y+16=2(x+8)](https://tex.z-dn.net/?f=y%2B16%3D2%28x%2B8%29)
![y+16=2x+16](https://tex.z-dn.net/?f=y%2B16%3D2x%2B16)
Subtract 16 from both sides.
![y=2x](https://tex.z-dn.net/?f=y%3D2x)
Therefore, the equation of line b is
.
