X-intercept is -1 implies line passes through (-1,0). 
So point slope form is
y - 0 = -2 (x -(-1) )
>> y  = -2 (x +1)   <----- FINAL ANSWER

Answer:
Slope is 2
Step-by-step explanation:
(-2, -4) and (2, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4+4)/(2+2)
m=8/4
m = 2
 
        
             
        
        
        
61/4 % converted into a decimal is 15.25
