B) (4, 3)
C) (4, 1)
D) (4, 2)
E) (3, 1)
Which point is in quadrant II?

B) B
C) C
D) D
E) none of these.
Second one
A (1, 1)
B (2, 3)
C (5, 3)
The first thing to do is to plot these here : https://www.desmos.com/calculator/viqqgx48qv
We can find the coordinates of D by noting that we had to subtract 1 from the x coordinate of (2,3) and 2 from the y coordinate of (2,3) to get (1,1)
This implies that if we subtract 1 from the x coordinate of (5, 3) and 2 from its y coordinate we get
(5 - 1, 3 - 2) = (4, 1) = D
