Please help me with this math question!?

Question

Please give me the x and y intercepts so I can graph this:

A girl goes for a walk. She leaves home, walks 2 blocks in 5 mins at a constant speed, she forgets her keys and runs home in 1 minute . While at her door it takes her 1 minutes to find her keys and lock the door. She then walks 5 blocks in 15 minutes, and then decides to jog home. It takes her 7 minutes to jog home. Draw a graph of the girl's distance from home (in blocks) as a function of time.

b) Draw a graph for the number of blocks that the girl walked as a function of time.

Answer 1

let x = time in minutes and y = distance in blocks
Start at 0,0
Next point is 5,2 (5 minutes, 2 blocks)
Next point is 6,0
Next point is 7,0
Next point is 22,5
Final point is 29,0

Second one is similar, but use |y| rather than distance from home
First point is 5,2
Second point is 6,4 (she went 2 blocks)
third point is 7,4
fourth point is 22,9
final point is 29,14
