Given:
Equation of line 
.
To find:
The equation of line that goes through the point ( − 21 , 2 ) and is perpendicular to the given line.
Solution:
The given equation of line can be written as
Slope of line is
Product of slopes of two perpendicular lines is -1. So, slope of perpendicular line is
![[\because m_1=\dfrac{7}{4}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20m_1%3D%5Cdfrac%7B7%7D%7B4%7D%5D)
Now, the slope of perpendicular line is 
and it goes through (-21,2). So, the equation of line is
Therefore, the required equation in slope intercept form is .
Answer:
$120
Step-by-step explanation:
Calculation for what was her commission
Since she sold the amount of $1,500 in the month of November in which we were told that she earns the commission of 8% for all sales which means that her commission will be calculated as :
Using this formula
Commission=November sales* Sales commission
Let plug in the formula
Commission=$1,500*8%
Commission= $120
Therefore what her commission will be is $120
