Question

If the point (2k + 1, k-2) lies on the graph or the equation 2x +y + 5 = 0, find the value of K​

Answer 1

Answer:

Since the point lies on the graph, it must satisfy the equation.

Step-by-step explanation:

Hence put the value of x and y i.e., (2k 3, k + 2) in the equation 2x + 3y + 15 = 0

So, 2 (2k-3) + 3(k + 2) + 15 = 0

4k 6+ 3k + 6 + 15 = 0 -

7k = -15

k = -15/7
