Answer:
y=3x-10
Step-by-step explanation:
For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.
(y-y1)=m(x-x1)
(y-2)=3(x-4)
y-2=3x-12
y=3x-10
To check, you can plug the coordinates into the equation.
y=3x-10
(2)=3(4)-10
2=12-10
2=2
Just move y to the side with x and move 4 to the other end
Answer:
it is linear association
Step-by-step explanation:
Cos(x) is infinitely differentiable, can be expanded using Taylor's series.
The series about c can be expressed as

Substituting cos(x), c= π /4,we have

and since




we can simplify the expansion to

Note that the sign pattern is - - + + - - + + - - ..... following the sign pattern of the derivatives of cos(x).
