If it has the negative so the answer will be negative but if it doesn't have the negative so the answer is positive because if you want to find the m you should divide the both sides of the equation by the factor of m: 
-4m = 1.75 ⇒ -4m/-4 = 1.75/-4 ⇒ m = 1.75/-4 ⇒ m = -0.4375 
4m = 1.75 ⇒ 4m/4 = 1.75/4 ⇒ m = 1.75/4 ⇒ m = 0.4375 :)))
i hope this is helpful 
have a nice day

 Answer:
65.56°
Step-by-step explanation:
We know that if we take dot product of two vectors then it is equal to the product of magnitudes of the vectors and cosine of the angle between them
That is let p and q be any two vectors and A be the angle between them
So, p·q=|p|*|q|*cosA
⇒
Given u=-8i-3j and v=-8i+8j


let A be angle before u and v
therefore, 
⇒
Therefore angle between u and v is 65.56°
