Question

3x+ky = "-2" this is the equation of a line. a point satisfies this equation of line such that its abscissa is 2 and the ordinate is four times the abscissa. find the value of k

Answer 1

Answer:

k=-1

Step-by-step explanation:

3x+ky=-2

abscissa is x then

x = 2

ordinate is 4x

then y = 4*2 = 8

3(2)+k(8)= -2

6+8k=-2

k=-1
