Draw the diagram that represents the locus in each of the following situations. What is the locus of each?

Going down an escalator

Sitting in a seat on a Ferris wheel as it rotates.

All the points that are 2 cm from a parabola.

All the points that are 5 cm above a line.

I dont have a clue as to how drawing these diagrams will help me represent a locus I dont understand the question do I need to point out the locus in the diagram? Will there be an equation what do I have to do plz help me :cry:

Use your imagination! Imagine yourself going down an escalator or around on a ferris wheel. What does your path look like? That's what "locus" means.

I can draw the diagrams but I dont know what the locus is in each diagram

ok ...

a) down an escalator a slanted line?

b)A circle?

c)Still a parabola but each point moves 2 cm up or down

d) still a straight line 5 cm above original line

I have written this but how do I show this is this what the question is asking?
