Answer:
x = (-12/7 , 0)
y= (0,4)
Step-by-step explanation:
Plug y=0 into the equation and solve the resulting equation 7x=−12 for x
7x = -12
/7      /7
x = -12/7     and y =0
Plug x=0 into the equation and solve the resulting equation −3y=−12 for y
-3y = -12
/-3     -3
Y = 4        and X = 0
 
        
             
        
        
        
Answer:
1 1/2
Step-by-step explanation:
2 2/3 - 1 1/6 = ?
The LCD here is 6.  Convert 2 2/3 so that the denominator is 6:
2 2/3 = 2 4/6
Then subtract 1 1/6 from 2 4/6:  We get 1 3/6, or 1 1/2
 
        
             
        
        
        
In a line with negative slope, as x increase, y decreases.
 
        
             
        
        
        
It would travel 65 times 4 = 260 miles
