Step-by-step explanation:
use sum of angles on a straight line
Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points
in order to do so
recall that,
![\displaystyle m_{ \text{perpendicular}} = - \frac{1}{m}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20m_%7B%20%5Ctext%7Bperpendicular%7D%7D%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7Bm%7D%20)
we got from our given equation that m=2
because equation of a line is y=mx+b
thus
![\displaystyle m_{ \text{perpendicular}} = - \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20m_%7B%20%5Ctext%7Bperpendicular%7D%7D%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20)
remember that, when we want to figure out perpendicular line or parallel line we should the formula given by
![\displaystyle y - y_{1} = m(x - x_{1})](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20-%20%20y_%7B1%7D%20%3D%20m%28x%20-%20%20x_%7B1%7D%29)
since we got our perpendicular m is -½,
and
, substitute
![\displaystyle y - 5 = - \frac{1}{2} (x - 6)](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20-%20%205%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20%28x%20-%20%206%29)
to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:
![\displaystyle y - 5 = - \frac{1}{2} x + 3](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20-%20%205%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20x%20%20%2B%203)
add 5 to both sides:
![\displaystyle y = - \frac{1}{2} x + 8](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20y%20%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20x%20%20%2B%208)
hence,
our answer choice is B
Answer:
x^7y^8z^7 may be it is answer cause i think yhiai is basic of indices. U just have to add with it's common variable's powrt.
