To be apart of that state for atleast ten years is one.
Acc. to midpoint theorem,
15={(2x+9) + (4x-15)}/2
⇒ 30=2x+9+4x-15
⇒ 30-9+15=6x
⇒ 36/6=x
⇒6=x
WZ= 4x-15
=4*6-15
=24-15=9

You can tell because every time the x value increases by 1, the y value increases by exactly 1/2 every time
Fractions not roots
