The only line that would be parallel to this line and still hit that point would be that line. Is that an option, or did the paper maybe say (4,-4) or maybe even say to draw the line perpendicular to the point?
Answer:
2 hours
Step-by-step explanation:
Given
![Contractor: 81x + 108](https://tex.z-dn.net/?f=Contractor%3A%2081x%20%2B%20108)
![Electronic\ Store: 103x + 64](https://tex.z-dn.net/?f=Electronic%5C%20Store%3A%20103x%20%2B%2064)
Required
Determine the hours when the charges are the same
To do this, we simply equate both expressions:
![Contractor = Electronic\ Store](https://tex.z-dn.net/?f=Contractor%20%3D%20Electronic%5C%20Store)
![81x + 108 = 103x + 64](https://tex.z-dn.net/?f=81x%20%2B%20108%20%3D%20103x%20%2B%2064)

![81x - 103x = 64 - 108](https://tex.z-dn.net/?f=81x%20-%20103x%20%3D%2064%20-%20108)
![-22x = -44](https://tex.z-dn.net/?f=-22x%20%3D%20-44)
Divide both sides by -22
![x =2](https://tex.z-dn.net/?f=x%20%3D2)
