Answer:
can u please provide us with the graph so that we can help u
Step-by-step explanation:
 
        
             
        
        
        
Y = mx + b, m = slope and b = y-intercept
Thus the answer is y = -3x + 7
        
             
        
        
        
The arc length (s) is given in terms of the radius (r) and central angle (θ) by
  s = r*θ . . . . . . . where θ is in radians
For your arc, the length is
  s = (15 ft)*(π/4) ≈ 11.78 ft
_____
45° can be converted to radians by multiplying by π/180°.
  45° * (π/180°) = π*(45/180) = π/4 . . . . radians
        
             
        
        
        
Since C only has two and although it may look like B has three terms, when the letters are joined together like that they are basically just become one big term, so your answer would be A.
