Y = mx + c 
m = 2
y = 2x + c
At (5, 0)
0 = 2(5) + c
c = -10
y = 2x - 10
        
             
        
        
        
Y=mx+b
Y= -14(x-5)+4
Y= -14x+70+4
Y= -14x+74 
Plot (0,74) 
Then move down 14 then over left 1
        
                    
             
        
        
        
Answer:
84.4 gallons to the nearest tenth.
Step-by-step explanation:
Average usage = miles travelled  / gallons used  so:
6.3 = 532 / gallons used
Gallons used  =   532 / 6.3
= 84.44.
 
        
             
        
        
        
Answer:
w = -5
Step-by-step explanation:
Hello there!
9+7w-9=5w-10
Add 9 and -9 since we can add those
7w=5w-10
Use subtraction Prop of Equality (combining/simplifying like terms)
2w = -10
Now isolate the w by dividing 2w by 2 and use the division prop of equality 
w = -5
Hope this helps. Feel free to comment for further explanation.
