The slope of a line at a given point is equal to its derivative at that point:
2xdx + 2ydy = 0
-2ydy = 2xdx
dy/dx = -x/y
Slope = -(4/1)
= -4
Equation:
y - 1 = -4(x - 4)
Answer:
4
Step-by-step explanation:
x^2/ y^4
Let x=8 and y=2
8^2 / 2^4
PEMDAS says powers first
64 / 16
Divide next

Step-by-step explanation:
When a number has the same variable as another, you can add or subtract them
So for the first one, you can do
(But don't forget the !)
So it is:
