Answer:
a = -1, b = -2.5
Step-by-step explanation:
Rule for the dilation of a vector by a scale factor of k is,
(x, y) → (kx, ky)
BY using this rule for a vector by a scale factor of 2.5
→
Followed by the rotation by 90° Or radians,
Rule for rotation of a vector by 90° is,
(x, y) → (-y, x)
By this rule vector will become,
→
If we represent this vector by ,
Then a = -1 and b = -2.5 will be the answer.
