Question

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

Answer 1

$\bold{Answer :}$

The straight line is

y = 2x + 5 ...(i)

Let us take the point as (k, 7)

Since (k, 7) lies on (i), it satisfies the equation.

Then,

7 = 2k + 5

or, 2k = 7 - 5

or, 2k = 2

or, k = 2/2

or, k = 1

So, we get k = 1

i.e. $\bold{? = 1}$
