Answer:
Step-by-step explanation:
The equation of the given line:
This equation is in the form 
. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line:
If she wants to earn $91, you would need to divide $91 by 13 to determine the number of hours she needs to work:
