Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula

where
m is the slope
( x1 , y1) is the point
From the question the point is (-5,-2) and the slope is - 6/5
The equation of the line is

We have the final answer as

Hope this helps you
 
        
             
        
        
        
The y intercept is 2.25 and x intercept is -3
        
                    
             
        
        
        
The distance that will separate each rest stop is 4 kilometers.
<h3>What is the distance?</h3>
Division is the process of parting a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
The distance = length of the trail / number of rest stops 
20 km / 5 = 4km
