choose all answers that are correct.

a. y-3=-1/2(x-4)

b. y-4=1/2(x-3)

c. y-3=1/2(x+1)

d. y-1=1/2(x+3)

24

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
