hard time to visualise a case in Coordinate Geometry

In the xy-plane, if line k has negative slope and passes through the point (s, -2), is the x-intercept of line k positive?
(1) s = 0
(2) The y-intercept of line k is negative.

I am able to reach upto the answer ie D.

I was trying to visualise all the cases as S can either be 0, (-)ve or (+)ve.

However, I am not able to visualise the case where S is (+)ve . Please help

This might not totally related to the question asked above, but clarifying whether my understanding is correct?

  1. if x intercept of a line is zero – that means the line passes thru the origin and nothing can be deduced about its slope (+ve or -ve)
  2. if y intercept of a line is zero – that means the line passes thru the origin and nothing can be deduced about its slope (+ve or -ve)

Hi TC,

Yes man you are right about the x – intercept and y – intercepts of a line zero.

Please find attached image for the point (s,-2) where S is positive.

Hope this is clear 🙂
