Question

if a point bracket K - 3, k + 2 bracket lies on a graph of equation 2 X + 3 Y + 15 =0 find value of key

Answer 1

(k-3 , k+2)  ---> x = k-3 , y = k+2 2x + 3y +15=0 by substituting  the values in eq. we get, 2 (k-3) + 3 (k+2) = -15 2k - 6 +3k +6 = -15 5k = - 15 k = -3   is the ans..   hope this helps.. Mark as the brainliest pls..
