Skew lines are lines that are not pararell or perpendicular.
The only lines that fit this explanation are AE and GF

Answer:
   see attached
Step-by-step explanation:
The x-coordinate of the vertex is given by ...
   x = -b/(2a)
for f(x) = ax^2 +bx +c.
We see that the vertex is at x = 1, and we are given a = -16. Then we can find "b" from ...
   1 = -b/(2(-16))
   32 = b
We know the y-intercept of the equation is 5 (the starting height), so the equation must be ...
   h(t) = -16t^2 +32t +5 . . . . . matches the last choice
 
        
             
        
        
        
Answer:
17) A(-1,1) B(-1,4) C(5,1)
18) (From origin moving rightwards)
      A(0,0) B(a, 0) C(a,a) D(0,a)
Step-by-step explanation:
17) You just count the steps, how many steps left, right, up, or down
18) The first point is at the origin, so 0,0
     The second point that lies on the x axis is (a,0) as it is a distance from the origin, 0 because it's on the x-axis. 
      The third point is (a,a) because it is a distance to the right of the origin AND a distance upwards from the x axis. 
       The fourth point (0,a) because it is on the vertical line (0) and is a distance above the origin.
