Question

find the value of k so that (2,1) is a solution of the equation 2x+3y+k=0 hence find the point at which it cuts the x axis​

Answer 1

Answer:

Given:–

The equation is,

$2x + 3y + k = 0$

And (2,1) is a solution of the Equation,

Substitute the point in the equation

$2(2) + 3 + k = 0$

$k + 7 = 0$

$k = - 7$

So, The value of k is -7.
