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?
