Question

(2,?) is on the line y= 3/7x+5. What is the other half of the coordinate?

Answer 1

(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)

Answer 2

the other half is -7
