Answer: c

Explanation:

A direct proportion has a formula that is written this way: y=kx

what does that mean ?

There is an image at the end to make you understand .

a direct proportion is a straight line that must go from the origin . why?

  • simply beacuse it equals 0 in 0 . y=k*0=0 . so the coordinates of that point are (0,0) wich is the origin !
  • a direct proportion must have a constant slope to make it go straight or it wouldn't be a straight line . i left an image to make it clear
  • a diect proprtion must not have a slope of 1 . it can be 1, 2,100000 or 0.5
  • its graph must be linear
