Answer: y=8
Step-by-step explanation:
 
        
                    
             
        
        
        
Slope Formula - (y² - y¹) / (x² - x¹)
(1, 7) 
x¹ = 1
y¹ = 7
(-4, -8)
x² = -4
y² = -8
-8 - 7 = -15
-4 - 1 = -5
Simplify - -15/-5
-15/5 = -3
Your answer is -3.
Hope this Helps!! 
 
        
             
        
        
        
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = 4
a = coefficient of squared term = 1
c = constant term = 7
Using the values, we get:
 So, the correct answer to this question is option A

X-y is positive when y is further away from 0, compared to x. In other words, when y is a larger negative
For example
x = -2
y = -5
x-y = -2-(-5) = -2+5 = 3
