$-4/3$

Explanation:

Here

$y=mx$

is the given eq, with $m$ being the slope of the given line. Therefore, the slope of this line is $3/4$ $(m)$ .

But the slope of the line perpendicular to the given line is $=-1/m$ , so the answer is $=-1/(3/4)$

which is $=-4/3$ .

The perpendicular slope is $-4/3$ .

Explanation:

Given:

$y=3/4x$

The slope that is perpendicular to $3/4$ is its negative reciprocal, which is $-4/3$ .

Mathematically

$m_1m_2=-1$ ,

where $m_1$ is the given slope and $m_2$ is the perpendicular slope.

$3/4m_2=-1$

Multiply both sides by $4/3$ .

$color(red)cancel(color(black)(4))^1/color(red)cancel(color(black)(3))^1xxcolor(red)cancel(color(black)(3))^1/color(red)cancel(color(black)(4))^1m_2=-1xx4/3$

Simplify.

$m_2=-4/3$
