Question

For what value of k does the point k,- 4 lies on the line 2x - y = -6

Answer 1

for (k, -4) to lie on the line 2x - y = -6

x = k and y = -4 should satisfy the equation

2x - y = -6

2k -(-4) = -6

2k + 4 = -6

2k = - 6 - 4

2k = -10

k = -5

Hence, for k = -5, point (k, -4) lies on the line 2x - y = -6
