Best ResponseYou've already chosen the best response.0no, that would be the slope of any parallel line you are asked for a perpendicular line

Best ResponseYou've already chosen the best response.0in english (math english) it is the "negative reciprocal" i.e. flip it and change the sign

Best ResponseYou've already chosen the best response.0now use the point slope formula to find the equation, since you have a point and the slope

Best ResponseYou've already chosen the best response.0multiply out and get \[y3=\frac{7}{5}x7\] oh look the fractions are gone, but now you add \(3\) to both sides
