Best ResponseYou've already chosen the best response.0Perpendicular lines have opposite reciprocal slope. If we say the slope of line k is \(m\), then the slope of line p would have to be \((\frac{ 1 }{ m})\). What's \[m * \frac{ 1 }{ m }\]

Best ResponseYou've already chosen the best response.0right, so we know the result for A is 1.

Best ResponseYou've already chosen the best response.0That's what we just did. I was just restating the result

Best ResponseYou've already chosen the best response.0I don't understand how we got that....

Best ResponseYou've already chosen the best response.0we got 1 from the multiplication you did. m*(1/m)

Best ResponseYou've already chosen the best response.0Perpendicular lines have opposite reciprocal slope. If we say the slope of line k is m, then the slope of line p would have to be (−1/m).

Best ResponseYou've already chosen the best response.0oh okay. but for the problem itself it didn't give the slope

Best ResponseYou've already chosen the best response.0we don't need to know the slope. Knowing the relationship between the two lines is enough because they don't ask for the actual slopes. They only ask for their products

Best ResponseYou've already chosen the best response.0now we look at B. It says line p passes through the origin, so that means its yintercept is 0. We don't need to know the yintercept of line k because any number multiplied by 0, is 0. That means the result for B is 0.

Best ResponseYou've already chosen the best response.0Okay so i get B but for A how do we know it's a positive slope and not a negative one?

Best ResponseYou've already chosen the best response.0it doesn't matter. If we said k had a slope of m, then the opposite reciprocal of that would be 1/m. When you multiply you'd still get 1

Best ResponseYou've already chosen the best response.0OHHHHHHHHHHHHHHHHHHHHHHHHHHHH because they're perpendicular they will automatically be a negative for the product!!!!!!!!!!!!!!
