Question

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

Answer 1

y=3/7(2)+5
y= 6/7+5
y= 6/7+ 35/7
y= 41/7

Answer 2

The coordinate of (2,y) is 5.85 such that the given point lies on line
`y=(3)/(7)x+5`.

Explanation:

Given : Equation of line
`y=(3)/(7)x+5`

We have to find the value of y coordinate of point (2,y) such that the given point lies on line
`y=(3)/(7)x+5`.

Since, the point lies on the line
`y=(3)/(7)x+5`

So (2,y) satisfies the equation of line
`y=(3)/(7)x+5`

Put x = 2 and y = y, we have,

`y=(3)/(7)(2)+5`

`y=(6)/(7)+5`

Take LCM, we have

LCM (7,1) = 7

`y=(6+35)/(7)`

⇒
`y=(41)/(7)=5.85`

Thus, The coordinate of (2,y) is 5.85 such that the given point lies on line
`y=(3)/(7)x+5`.
