Answer:
Step-by-step explanation:
m = slope where
m = rise / run
rise = y2 - y1  
run = x2 - x1
where  
the given point P1 = (7, -12) 
and is in the form of (x1,y1)  
and 
the given point P2 = (-9,36)  
is  in   the   form  of   (x2,y2)
then
m =  ( y2 - y1 ) / ( x2 - x1 )
m = ( 36 - (-12) ) / ( -9 -7 )
m = ( 36 + 12 ) /  ( - 16 )
m =  48 /  - 16
m = - 3
the slope is negative 3
slope = - 3
 
 
        
             
        
        
        
it would be y = -12/5. Hes the work. hope this helps!
