Question

for what value of k, does the point (-1,2) lies on the graph of the linear equation 4x+ky=6?

Answer 1

Answer:

The value of k is 5.

Step-by-step explanation:

We know that the abscissa is the x coordinate and ordinate is y coordinate

Now in (-1,2), (-1) is the x coordinate and 2 is the y coordinate

It means x = -1 and y = 2

Put these values in the equation

So , now the equation looks somewhat like this

4 (-1) + k(2) = 6

》-4 + 2k = 6

》 2k = 6 -(-4) = 6 + 4 = 10

》 k = 10/2 = 5

Hence required value of k is 5.
