Question

find the value of k if the point (4, -2) lies on the graph of 2x=ky+3​

Answer 1

Answer:

$k = - \frac{5}{2}$

Step-by-step explanation:

$2x = ky + 3 \\ \\ put \: \: x = 4 \: \: \: \: \: \: \: y = - 2 \\ \\ 2(4) = k( - 2) + 3 \\ \\ 8 = 3 - 2k \\ \\ \\ - 2k = 8 - 3 \\ \\ - 2k = 5 \\ \\ k = - \frac{5}{2}$

Answer 2

By putting value of x and y that is 4, -2

In the equation, and solving it..
