Answer:
12/5
Step-by-step explanation:
m= slope
m=Y2-Y1/X2-X1
Y2=5, Y1=-7, X2=3, X1=-2
Substitute into equation
m=5-(-7)/3-(-2)
m=5+7/3+2
m=12/5 
slope is 12/5
 
        
             
        
        
        
Answer:
(a,b)------>(-1,-7)let
now
m(x-a)=(y-b)
2(x+1)=(y+7)(where m=slope
2x+2=y+7
2x-y=7-2
2x-y=5 is a required equation.
