Answer:

k ∈ R -{{\frac{4}{3}}

Step-by-step explanation:

For no solution: \frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}\\

x^2+0y - 4 = 0 \\(a_1 = 1 , b_1 = 0 , c_1=-4)\\\\2x+ky-3=0\\(a_2 = 2 , b_2 = k , c_2=-3)\\

\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}\\\\\frac{1}{2} = \frac{0}{k} \neq \frac{-4}{-3}\\\\from \frac{1}{2} = \frac{0}{k} :\\

k ∈ R

also, k \neq \frac{4}{3}\\\\

∴ k ∈ R -{{\frac{4}{3}}
