15. If the point (5,k) lies on the line represented by the equation 2x + y = 9, the value of k is....

guajiro [1.7K]

Answer:

The answer is C.

Step-by-step explanation:

Given that (5,k) lies on the line that has the equation of 2x + y = 9. So in order to find k, you have to substitute the coordinates into the equation :

$2x + y = 9$

Let x = 5,

Let y = k,

$2(5) + k = 9$

$10 + k = 9$

$k = 9 - 10$

$k = - 1$
