Answer:
1. During part 2. The y-axis (line going up) represents his distance. At part 1, his distance stays the same because he is sitting in the park. At part 2 we see the line go down, which means his distance from home is decreasing.
2.At part 3. His distance stays the same, which represents him waiting in line. We know this because the line stays at the same distance and the time increases(this is the x-axis)
3. There would be another part of the graph. If he had stopped again, there would have been another straight line with the distance the same and the time increasing.

Answer:
$300
Step-by-step explanation:
Since 20% is equal to 1/5, you should multiply $60 by 5 to get $300 as the original cost and as your answer.
According to your text first equation is
y = 3x+2
second equation is
y = Ix-1I + 1
Definition of our absolute value Ix-1I is
1) we take x-1 with condition x-1≥0 => x≥1
2) we take -(x-1) = -x+1 with x<1
Let's form the first system with condition x≥1
y= 3x+2 and y=x-1+1=> y=x
If the left sides of the equations are equal, than the right sides are equal too
3x+2=x => 3x-x=-2 => 2x=-2 => x=-1
This solution we can't accept because it does not meet the condition
x≥1
Lets's form the second system with condition x<1
y=3x+2 and y= -x+1+1 =. y = -x+2
In the same way as previous the right sides are equal =>
3x+2=-x+2 => 3x+x = +2-2 => 4x=0 => x=0
We accept this solution bacause its meet with condition x<1
When we replace this solution in equation y=3x+2 we got
y=3*0+2=2 Only one solution is (x,y) = (0,2)
Good luck !!!!!
