Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, 
, with 0 in the function, and solve for time 
:
Since time cannot be negative, the solution is
seconds.
Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>

Well, since we do not know the line, the basic slope formula is Y = mX + B
So look at the line and see where is crosses the y axis (the vertical) and that is your B in the formula or the "Y-intercept" as an example I will used the number 1. Then on your line pick two points, I will use the points (4,4) and (1,2) as an example. To find your slope take the Ys in those points (the second number) and subtract them 4 - 2 = 2. Then subtract the Xs (the first numbers) 4 - 1 = 3. Lastly, take the 2 and divide it by the 3 (yes it can be a fraction) and that is your slope. So the entire answer with my examples would be Y =
x + 1 with 1 being my y-intercept and 2/3 being my slope
