Step 1 ：The slope of line $c$ is $-\frac{3}{7}$. The slope of a line perpendicular to line $c$ is the negative reciprocal of the slope of line $c$. Therefore, the slope of line $d$ is $-\frac{1}{-\frac{3}{7}}=\frac{7}{3}$.

Step 2 ：We know that line $d$ passes through the point $(2,4)$. We can use the point-slope form of a line to find the equation of line $d$. The point-slope form of a line is $y-y_1=m(x-x_1)$, where $(x_1,y_1)$ is a point on the line and $m$ is the slope of the line.

Step 3 ：Substituting the given point and the slope into the point-slope form, we get $y-4=\frac{7}{3}(x-2)$.

Step 4 ：Solving for $y$, we get $y=\frac{7}{3}x-\frac{14}{3}+4=\frac{7}{3}x-\frac{2}{3}$.

Step 5 ：Therefore, the equation of line $d$ is $y=\frac{7}{3}x-\frac{2}{3}$.

Step 6 ：Using python code to simplify the final answer, we get \(\boxed{y=\frac{7}{3}x-\frac{2}{3}}\)
