Đường thẳng \(d:y = mx + n\) và  parabol  \(\left( P \right):y = a{x^2}\)\(\left( {a \ne 0} \right)\) không cắt nhau khi phương trình \(a{x^2} = mx + n\)

\(\left( {d'} \right):y = 5x - 24\).

\(\left( {d'} \right):y = 5x +24\).

\(\left( {d'} \right):y = 24x - 5\).

\(\left( {d'} \right):y = 5x - \dfrac{{25}}{4}\).
