Point slope from would be 12x-y+26=0.
Black is the equation, 12x-y+26=0.
- Orange is <em>y-14=12(x+1)</em>
- Blue is <em>y-14=12(x-1)</em>
- Red is <em>y+14=12(x-1)</em>
- Green is <em>y-14=-12(x+1)</em>
Answer:
I think is -x + 105/42y
Step-by-step explanation:
2(3/10)x - 5/7y - 4(5/6)y - 2(4/5)x
6/10x - 5/7y - 20/6y - 8/5x
6/10x - 8/5x - 5/7y - 20/6y
6-16/10x - 35+140/42y
-10/10x + 105/42y
-x + 105/42y
7 because 7•3=21 and if he has as twice much as you 7•2=14 & 14+7=21 books together
