Answer:
It is B. hyperbola, 45 degrees.
SteIt is p-by-step explanation:
If we rotate the standard form  x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.
 xy = -2.5 comes from x^2 - y^2 = -5  being rotated 45 degrees.
 
        
                    
             
        
        
        
Step-by-step explanation:
the line passes through (0,-2) and perpendicular to the graph of y=5x+7.
solution :
the slope = -1/5
the equation :
y+2 = -1/5 (x-0) 
y = -1/5x - 2
