Question

If the point (2, k) lies on the line 2x+ y+5=0 then value of k is

Answer 1

Answer:

-9

Step-by-step explanation:

here x=2 so put it in the equation you get y=k=-9

Answer 2

Step-by-step explanation:

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

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
