Question

find the value of K if (3,4)lies on the graph of the equation Kx = 2y + k ​

Answer 1

Step-by-step explanation:

Since, the point (x = 3, y = 4) lies on the equation 3y = ax + 7, then the equation will be , satisfied by the point.

Now, put x = 3 and y = 4 in given equation, we get

3(4) = a (3)+7

⇒ 12 = 3a+7

⇒ 3a = 12 – 7

⇒ 3a = 5

Hence, the value of a is 5/3

Answer 2

Answer:

k=4

Step-by-step explanation:

kx=2y+k

if (3,4) lies on line

then it will satisfy equation of line

so

we will put

x= 3 and y=4

so

3k=2(4) +k

3k=8+k

2k=8

k=4
