Question

if (0,1) is a solution of 5x+ky=20 then k=​

Answer 1

Step-by-step explanation:

5×0+k×1=20

0+k=20

k=20

hence k=20

Answer 2

If (0,1) is a solution of 5x+ky=20 then k = 20.

If a point (x,y) is a solution of any line, it means that if we put the abcisssa and the ordinate of the point in the equation of the line, it satifies the equation of line.

Given, the equation of the line is : 5x + ky = 20.

And, the point is (0,1).

Now, we have to find the value of k, for which the point is the solution of the given line.

As already discussed, we have to put the abcissa and ordinate of the point in the equation of line, and it will satisfy the equation, because it is a solution for the line.

So, putting x = 0  and y = 1, in the equation of line, we get:

5(0) + k(1) = 20

⇒k = 20.
