The line perpendicular to $y = 4x - 10$ will have a slope that is the negative reciprocal of the slope of the given line $y = 4x - 10$. The slope of $y = 4x - 10$ is $4$, so the perpendicular line will have a slope of $-\frac{1}{4}$ $negative reciprocal$. Given that the line passes through the origin $$0, 0$$, we can use the point-slope form of a line, $y - y_1 = m$x - x_1$$, with the slope $m = -\frac{1}{4}$ and the point $$x_1, y_1$ = $0, 0$$. $4$y - 0 = -\frac{1}{4}$x - 0$$$\$ $y = -\frac{1}{4}x$ Therefore, the reduced equation of the straight line that is perpendicular to $y = 4x - 10$ and passes through the origin is $y = -\frac{1}{4}x$
