Which of the following equations describes all points on a horizontal line that passes through the point (-3, 7)? (1) y = 7
(3) x = -3
(2) y = -3x + 7
(4) y = 7x-3

correct answer is b. 27/8

step-by-step explanation:

the answer is b.

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
