Would the y vs. t plot look like a parabola?

[Mitchtwitchita]

Can anyone please explain to me what a y vs. t and a v vs. t plot would look like for an object projected vertically upward with an initial velocity of 34.3 m/s?

Would the y vs. t plot look like a parabola?
Would the v vs. t plot look like a diagonal line starting at 34.3 m/s and ending at -34.3 m/s?

y vs t will look like a parabola, and v vs t will like like a line with negative slope, but not necessarily ending at -34m/s

Thanks!
