Sketch a few members of the straight lines through the origin. By eliminating parameters, derive a differential equation which describes this family.
Attempt
(since there are infinite gradients)
but the correct answer was: . I am not sure why.

Thanks. If instead the question was: find the differential equation for the straight lines through the point (2,3), what would the procedure be?
I tried using:
y = mx + c
3 = 2m + c
but differentiating it obviously wouldnt work, since there are only constants
