Answer:
m=-3/5
Step-by-step explanation:
Simplifying
3x + 5y = 7
Solving
3x + 5y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
3x + 5y + -5y = 7 + -5y
Combine like terms: 5y + -5y = 0
3x + 0 = 7 + -5y
3x = 7 + -5y
Divide each side by '3'.
x = 2.333333333 + -1.666666667y
Simplifying
x = 2.333333333 + -1.666666667y
 
        
             
        
        
        
Ok...
700 m = 0.7 km 
5 minutes = 5/60 hours 
Then, speed is:
S= 0.7 km / (5/60) hours = 8.4 km/hola
Good luck!

Y=radical 3
just cancel out the 2 on both sides
