Answer:
11
Step-by-step explanation:
15-4 = x
15-4 = 11
x = 11
to isolate x, you move 4 to the other side and it becomes 15-4 = x
 
        
             
        
        
        
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
 
        
             
        
        
        
-7x + y = -6    |add 7x to both sides
y = 7x - 6
the slope: m = 7
the y-intercept: y = -6
