The rate of change is +2
as an ordered pair it would be (1,-3),(2,-1)(3,1),(4,3)
N(2x+y) = x +1
Differentiate both sides, using the Chain Rule on the left side.
(1 / (2x + y)) * d(2x + y)/dx = 1
(1 / (2x + y)) * (2 + dy/dx) = 1
<span>Rearrange to isolate dy/dx.

The answer is 77. if you do it the opposite way and multiply
The zeroes are -1/2 and -2
last option
