Question

find the value of k for which the point (-1 , 3) lies on the graph of the equation 2x - y + k =0.

Answer 1

Here, x = -1 , y = 3

Put this value in the equation,
2(-1) - 3 + k = 0
-2 - 3 + k = 0
k = 5

Answer 2

Answer:

Step-by-step explanation:

Here, x = -1 , y = 3

Put this value in the equation,

2(-1) - 3 + k = 0

-2 - 3 + k = 0

k = 5
