Don't quote me but i'm pretty sure it is a right triangle 
        
                    
             
        
        
        
A: Slope-intercept form: y = 2 x − 1 Point-slope form: y − 7 = 2 ⋅ ( x − 4 )
B: Slope-intercept form: y = 4 x + 7 Point-slope form: y + 1 = 4 ⋅ ( x + 2 )
C: Slope-intercept form: y = 1/2 x − 8 Point-slope form: y + 4 = 1/2 ⋅ ( x − 8 )
 
        
             
        
        
        
X equal 7 so 49=x7 that is what I would do at least
        
             
        
        
        
(2,-2) would be the answer I think
