Perpendicular slopes:
$$m_1 = -\frac{ 1 }{ m_2 }$$

anonymous · Answer

In a linear equation the coefficient of x represents the slope.

anonymous · Answer

I dont know what any of that means

anonymous · Answer

Do you know what a slope is?

anonymous · Answer

yup

anonymous · Answer

If two lines are perpendicular to each other, their slopes will be opposite and negative to each other

anonymous · Answer

x = 1/x opposite
x = -x negative

anonymous · Answer

in your question, 5x is the slope

anonymous · Answer

what is the opposite and negative of 5x?
