Best ResponseYou've already chosen the best response.1correct! now the requested slope m1, is given by thie condition: \[\Large {m_1} \cdot \frac{5}{4} =  1\]

Best ResponseYou've already chosen the best response.1If I multiply both sides of my equation by 4 , I get: \[\Large {m_1} \cdot 5 =  4\] please divide both sides by 5, what do you get?

Best ResponseYou've already chosen the best response.0Remember that finding the perpendicular line of a line that we already know, we need to find the slope first (of the original line). Then, we have to find the reciprocal (a/b > b/a) and finally put a negative sign next to it (that's why it's called negative reciprocal).
