Step-by-step explanation:
slope: -4
y + 1 = -4(x - 0)
y + 1 = -4x + 0
y = -4x - 1
 
        
             
        
        
        
Answer: C. 5
Step-by-step explanation:See the attached picture. 
 
        
                    
             
        
        
        
For this case what you should do is use the following trigonometric relationship:
 tan (x) = C.O / C.A
 Where
 x: angle
 C.O: opposite leg
 C.A: adjoining catheto
 Substituting the values we have:
 tan (60) = long / short
 tan (60) = long / 2
 long = 2 * tan (60)
 long = 3.46
 Answer: 
 long = 3.46
