An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of 16.2 m/s and measures a time of 22.0 s before the rock returns to his hand. What is the acceleration due to gravity on this planet?

I have no clue how to answer this. I tried the equation V=Vo + at, but the answer i get (.736 m/s^2) is not right. How do I do this?

Show that the equation of the line having x-intercept 'a' and y-intercept 'b' is 'bx + ay = ab'?

That's all it says, and its only a worksheet, not out of my textbook. So I really don't know what is being asked. Any help would be appreciated!
