Question

Find the value of k, if (-1,1) is a solution of the equation 3x- ky = 8 , Also find the coordinates of another point lying on its graph.

Answer 1

ANSWER:-

(-1,1)

x = -1

y = 1

3x- ky = 8

= 3(-1) - k(1) = 8

= -3 - k = 8

= -3 -8 = k

= -11 = k

We get the equation as = 3x - (-11y) = 8

Now , for statement

Let's put value of x as "2"

3(2) - (-11y) = 8

6 + 11y = 8

11y = 8 -6

11y = 2

y = 2/11

so , points are = 2 , 2/11
