Answer 2

Answer:

Step-by-step explanation:

Given equation = 2x + 3y + 15 = 0

Given points = (2k – 3, k + 2)

We consider 2k - 3 as x and k +2 as y

So put these values in the equation.

That is,

=> 2(2k-3) + 3(k+2) + 15 =0

=> 4k-6 + 3k + 6 +15 =0

Now put the like terms together..That is

=> 4k + 3k + 6 + 15 - 6 = 0

=> 7k + 15 = 0

=> 7k = 0 - 15

=> 7k = - 15

=> k = -15/7

So i hope this helps you....
