Answer: y = -(2/3)x + 5
Step-by-step explanation:
The line has negative slope. So, option 2nd and 3rd can be eliminated.
y-intercept is at y = 5 when drawing line of best fit, so option 1st can be eliminated.
I want to believe the equation is,
f(x) = -5/x
This can be written as;
f(x) = y
y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
= 5x⁻²
Derivative at x=11,
dy/dx = 5(11)⁻²
= 5/(11²)
= 5/121
So, the derivative of f(x) = -5/x at x=11 is 5/121.
