Part 2)
Step-by-step explanation:
Part 1)
we know that
The equation of the line in slope intercept form is equal to
we have
Isolate the variable y
subtract 2x both sides
Divide by B both sides
Part 2)
we know that
The equation of the line in slope intercept form is equal to
we have
Isolate the variable y

Answer:
Option B is correct
the degree of rotation is,
Step-by-step explanation:
A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.
To find the degree of rotation using a standard rotation matrix i.e,
Given the matrix:
Now, equate the given matrix with standard matrix we have;
=
On comparing we get;
and
As,we know:
we get;
and
we get;
Therefore, the degree of rotation is,
