Answer:
Step-by-step explanation:
yes it is a geometric sequence
a1=3
r=-3/3=-1
Easy you multiply 4 times 7 which equals 28 so the answer is 4/7=16/28
Since you didn’t specify that it needed to be y as a function of x, all of the above equalities can be rewritten as functions. However, in case that you meant to imply that, A and B are both not valid for y as a simple function of x.
to find midpoint add the 2 x numbers and divide by 2
and add the 2 y numbers and divide by 2
X = -1 + 3 = 2, 2/2 =1
Y = 2 +4 = 6, 6/2 = 3
coordinate is (1,3)
