Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation

Linear approximation is a good way to approximate values of
as long as you stay close to the point
, but the farther you get from
, the worse your approximation.
We know that,

Next, we need to plug in the known values and calculate the value of
:

Then
.
The like terms would be 3x and 8x
I would use is over of equals percent over 100 is woudl be 120% and of would be 75 then you would put x over 75
3y + 2x =1
3y = - 2x + 1
y = - 2/3x + 1/3
slope : - 2/3
The answer will be 8.555555555555555556 (it's a repeating decimal)
