Remember that c is the initial height. Since we the rocket is in a 99-foot cliff, c=99. Also, we know that the velocity of the rocket is 122 ft/s; therefore v=122
Lets replace the values into the the vertical motion formula to get:
Notice that the rocket hits the ground at the bottom of the cliff, which means that the final height is 99-foot bellow its original position; therefore, our final height will be h=-99
Lets replace this into our equation to get:
Now we can apply the quadratic formula
where a=-16, b=122, and c=198
or 
or 
or 
Since the time can't be negative, we can conclude that the rocket hits the ground after 9 seconds.

The slope is ∞ , line is a vertical line parallel to y axis.
<h3>What is a Straight Line Function ?</h3>A straight line function is a function that can be represented by y = mx +c , where m is the slope of the line and c is the intercept on the y axis.
There are two points given for a line ,
The slope is represented by
m = ∞
which means the line is a vertical line parallel to y axis.
