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.

Look at the diagram below:

(1) s = 0. Directly gives the y-intercept of line k: (0, -2). Since the y-intercept of line k is negative and the slope of line k is negative too then the x-intercept of line k must also be negative. Sufficient.

(2) The y-intercept of line k is negative. The same here: since the y-intercept of line k is negative and the slope of line k is negative too then the x-intercept of line k must also be negative.

(1) s = 0
(2) The y-intercept of line k is negative.

The general equation of a line is y = mx+b. There are two things to consider here:

If the line passes through $$(s,-2)$$, then $$-2 = ms+b.$$
The x-intercept of a line is given by $$x = \frac{-b}{m}$$.

Now, since m is negative, the question is asking is b > 0?

(1) s = 0. From the first consideration above, this tells us that b = -2. Sufficient.

(2) The y-intercept is negative (b < 0). Sufficient.

Therefore, either statement is sufficient.

took some extra seconds to think of the possible options...
1 - x intercept is 0! statement 1 is sufficient.
2 - there is no possible way for x intercept to be positive - sufficient.

D must be the answer
