Answer:
![y=\dfrac{-3}{7}x-\dfrac{32}{7}](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B-3%7D%7B7%7Dx-%5Cdfrac%7B32%7D%7B7%7D)
Step-by-step explanation:
Given that,
A line 7x - 3y = 68 and containing the point (8, -8).
The equation can be written as :
![-3y=68-7x\\\\y=\dfrac{68}{-3}+\dfrac{7x}{3}\\\\y=\dfrac{7x}{3}+(\dfrac{-68}{3})](https://tex.z-dn.net/?f=-3y%3D68-7x%5C%5C%5C%5Cy%3D%5Cdfrac%7B68%7D%7B-3%7D%2B%5Cdfrac%7B7x%7D%7B3%7D%5C%5C%5C%5Cy%3D%5Cdfrac%7B7x%7D%7B3%7D%2B%28%5Cdfrac%7B-68%7D%7B3%7D%29)
The slope is :7/3
Line is perpendicular so use m = –3/7
![-8=(-\dfrac{3}{7})\times 8+b\\\\-8+\dfrac{3}{7}\times 8=b\\\\b=\dfrac{-32}{7}](https://tex.z-dn.net/?f=-8%3D%28-%5Cdfrac%7B3%7D%7B7%7D%29%5Ctimes%208%2Bb%5C%5C%5C%5C-8%2B%5Cdfrac%7B3%7D%7B7%7D%5Ctimes%208%3Db%5C%5C%5C%5Cb%3D%5Cdfrac%7B-32%7D%7B7%7D)
So, required equation is :
![y=\dfrac{-3}{7}x-\dfrac{32}{7}](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B-3%7D%7B7%7Dx-%5Cdfrac%7B32%7D%7B7%7D)

the way you can solve this is by removing all numbers in front of the selected number(in this case, 2 should be removed) then change all numbers behind to 0.
6 can go into 48 8 times. How I figured out?
Start multiplying from a small number like
6×6= 36
6×7=42
6×8= 48
until you see your number 48, or a number that is lower that 48, but can not go any higher than 48.
