i still dont know
Answer:
x=-y/3
y=-3x
Step-by-step explanation:
dy/dx=4x-y means 4x-y=0
dy/dx=x-2y also means x-2y=0 then
4x-y=x-2y
3x=-y
y=-3x
x=-y/3
Answer:
y =
- 8
y = -
+ 3
y =
- 8
y = 
Step-by-step explanation:
To know the pairs that are perpendicular lines, we need to understand what makes a line perpendicular to another.
Perpendicular lines generally have slopes;
m and
So, any of the pairs with a negative inverse value of slope will be perpendicular.
y =
- 8 slope = 
y =
slope = 
We see they are negative inverses
y =
- 8 slope = 
y =
slope = 
These are also negative inverses.
