Hello! 
The equation would be y= -2/6x + (-3). Since, the y-intercept is -3 and the slope/growth is -2/6 (it's decreasing). 
To find the slope just make a growth triangle. We go down twice (then to the right 6 times).
        
             
        
        
        
120/100 = x/15
100x = 1800 (Divide by 100 on both sides)
x = 18
