4y+1
Step-by-step explanation:
7y-3y=4y
-4+5=1
Answer:
Step-by-step explanation:
Unit vector is a vector with mangnitue 1 and we can find out the magnitude of the vector
with the following formula
![magnitude = \sqrt{x^{2}+y^{2}}](https://tex.z-dn.net/?f=magnitude%20%3D%20%5Csqrt%7Bx%5E%7B2%7D%2By%5E%7B2%7D%7D)
So in the given options whichever vector has magnitude 1 it will be a unit vector.
So if we put the values in the above mentioned formula
1.Magnitude of option A is not 1 so it is not a unit vector
2.Magnitude of option B is 1 so it is a unit vector
3.Magnitude of option C is 1 so it is a unit vector
4.Magnitude of option D is not 1 so it is not a unit vector
Answer:
y-b/m = x
Step-by-step explanation:
y = mx + b
~Subtract b to both sides
y - b = mx
~Divide m to both sides
y-b/m = x
Best of Luck!
