Answer:
Points apply to the given situation:
(a)The puppy will run into the wall after 5 seconds
(b)The slope is -4 ft per second since the puppy is running at a rate of 4 ft per second.
(c)The y-intercept is 20 ft because the puppy is 20 feet away from the wall.
Step-by-step explanation:
We have given,
A puppy is running at a rate = 4 feet per second
A wall is 20 feet away from puppy. That means initially puppy is 20 feet away from the wall.
So, time taken by puppy to reach the wall = 
i.e. time take by puppy to reach the wall =  = 5 seconds
  Now we write the points that apply to this situation:
(a)The puppy will run into the wall after 5 seconds
(b)The slope is -4 ft per second since the puppy is running at a rate of 4 ft per second. {Since the puppy is moving towards the wall that means horizontal distance is decreasing at a rate of -4 feet per second}
(c)The y-intercept is 20 ft because the puppy is 20 feet away from the wall.
 
        
             
        
        
        
Answer:
y=1/2x+1
Step-by-step explanation:
one dot on the 1 on the y axis 
then more one unit up and two units to the left 
and then from the first point (0,1) go one unit down 
and two to the right. then make the line with the three points 
 
        
             
        
        
        
You can can copy a line segment by making sure the line is straight
