Answer:

-4/3

Explanation:

We have given the slope of line . We have to find the slope of perpendicular line.

Since, we know that

Lines are perpendicular if their slopes are negative reciprocals to each other.

Let slope = m₁

Then, slope of perpendicular line is -1/m₁.

Slope = m₁ = 3/4

Slope of perpendicular line = -1/3/4 = -4/3

For this case, we have that by definition, if two lines are perpendicular, the product of their slopes is -1.

That is to say:


m_ {1} * m_ {2} = - 1

If line "l" has slope
m_ {1} = \frac {3} {4}

Then, the slope of the line perpendicular to it will be:


m_ {2} = \frac {-1} {\frac {3} {4}}\\m_ {2} = - \frac {4} {3}

Answer:


m_ {2} = - \frac {4} {3}
