Answer:
<h2>90°</h2>
Step-by-step explanation:
First you must calculate the module or the magnitude of both vectors
The module of u is:

The module of v is:

Now we calculate the scalar product between both vectors

Finally we know that the scalar product of two vectors is equal to:

Where
is the angle between the vectors u and v. Now we solve the equation for 

the answer is 90°
Whenever the scalar product of two vectors is equals to zero it means that the angle between them is 90 °
The value of n is 2, because if u do the multiplication then ur fine
Answer:
Step-by-step explanation:
hello :
y=mx+b
The linear equation when m = –6 and b = 1 is : y=-6x+1
The linear equation when m = 6 and b = -2 is : y=6x-2
The linear equation when m = 1 and b = 6 is : y=x+6
