Answer:
9(x + 2) = x - 6
9x+18=x-6
9x-x=-18-6
8x=-24
x=-24/8=-3 is your answer

Answer: Slope = 3/4  |  down 3 over 4
Step-by-step explanation: First I went into desmos graphing calc and then marked the two points (-20,-4) and on a seprete line marked (-12,-10)  and then i took a ruler and put up to my screen to see if there was a simplified answer (ex: 2/4 = 1/2) there was not so I just went down to the y line of the 2nd dot which turned out to be 3 and then just counted over to the dot which was 4 units.
 
        
             
        
        
        
Answers: b, d and e
b.The graph has a relative minimum
d. The graph has an x intercept at 3,0
e. the graph has an y intercept at 0,-15
 f(x)=(x+5)(x-3)
The given equation is in the form of f(x) = a(x-b)(x-c)
If 'a' is positive then graph has a relative minimum
If 'a' is negative then graph has a relative maximum
Here a=1 that is positive so graph has a relative minimum .
To find x intercept we set f(x) =0 and solve for x
0=(x+5)(x-3)
x+5 =0 -> x = -5 so x intercept is (-5,0)
x - 3=0 -> x= 3 so x intercept is (3,0)
To find y intercept we plug in 0 for x
y=(x+5)(x-3)
y=(0+5)(0-3) = -15
so y intercept is (0,-15)
 
        
                    
             
        
        
        
The pair of points defines a line with a slope of -1 is C. (10,3) and (15,-2)
