Answer 2

$<b><font face=Copper black size=4 colour=purple>$
Equation : 2x + 5y = 15

Point : ( k, 1 )

On comparing with ( x, y ), we get

x = k and y = 1

Putting these values in the equation.

2 ( k ) + 5 ( 1 ) = 15

2k + 5 = 15

2k = 15 - 5

2k = 10

k = 10 / 2

k = 5

Hence, the value of k = 5
