Equations are in slope-intercept form, so it is convenient to graph them by identifying the y-intercept, then finding another point or two based on the slope.

Of course, the y-intercept is the constant in the equation. This is where the line crosses the y-axis. The slope is the coefficient of x, and represents "rise" over "run", the number of units the line goes up for every unit to the right.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
