MCQ
The differential equation for the line $y = mx + c$ is (where $m$ and $c$ is arbitrary constant)
  • $\frac{{d^2y}}{{dx^2}} = 0$
  • B
    $\frac{{dy}}{{dx}} + m = 0$
  • C
    $\frac{{dy}}{{dx}} = 0$
  • D
    None of these

Answer

Correct option: A.
$\frac{{d^2y}}{{dx^2}} = 0$
a
(a) Differentiate it $w.r.t$. $x$, we get $\frac{{dy}}{{dx}} = m$.
