P(0,0) and Q(2a , 0)
Midpoint PQ
x = (x1 + x2)/2 and y = (y1 = y2)/2
Midpoint:
x = (2a +0)/2
= 2a / 2
= a
y = (0+ 0)/2
= 0/ 2
= 0
So midpoint PQ (a , 0)
Answer is the 1st option
(a, 0)
First you have to make the units same. it will be easier if you make both the units to be days.
2 weeks= 14days
ratio will be
34:14
if you can make it into simpler form, then make it. this answer can simplified into smaller form,thus,
34:14
17:7
the answer is 17:7
Changing the h value will move the graph horizontally left or right.
