What is the solution to this system of linear equations?
y − x = 6
y + x = −10
a) (−2, −8)
b) (−8, −2)
c) (6, −10)
d) (−10, 6)

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
