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 °

Answer:
Step-by-step explanation:
Answer:
C. -3
Step-by-step explanation:
Find the slope through rise/run.
Notice that every perfect point is away from each other and you need to go up 3 times and left once.
so the slope is rise/run = 3/-1 or -3/1 or -3
