(is on the line y= 3/7x+5. what is the other half of the coordinate?

(2, ?)  on y = (3/7)x + 5

y = (3/7)x + 5          x = 2,  y = ?

y = (3/7)2 + 5

y = (3/7)2 + 5

y = (6/7) + 5

y = (6 + 35)/5

y = 41/5  or 8.2

The other half of the coordinate is 41/5.

So (2 , ?) is   (2 , 41/5) or (2 , 8.2)

This is too long-standing now get out
