Question

What is the slope of the line perpendicular to the line
y=-3x + 2
Is it 1/3x+2 I'm not really sure

Answer 1

a perpendicular slope is a negative AND opposite reciprocal of the original slope.\[m_{p}=-\frac{ 1 }{ s }\]

Answer 2

s meaning slope. so if your original equation is \[y=\color{red}{-3}x+2\] the slope perpendicular to it would be \[y=\color{red}{-(-\frac{ 1 }{ 3 })}x+2\]

Answer 3

So yes, you're right, if the original slope is negative, you flip the original and take out the negative.

Answer 4

Okay thank you very much!!

Answer 5

no problem
