Answer:
- 1/2
Step-by-step explanation:
(0,0) (2,-1)
m = difference of y/difference of x = (-1 - 0) / (2 - 0) = - 1/2
y = - 1/2 x 
 
        
             
        
        
        
Y = mx + b
slope(m) = -6
(-2,-3)...x = -2 and y = -3
now we sub....we r looking for b, the y int
-3 = -6(-2) + b
-3 = 12 + b
-3-12 = b
-15 = b
so ur equation is : y = -6x - 15
        
             
        
        
        
Can you make the a bit more clear
