Best ResponseYou've already chosen the best response.2our first step is to convert each equation into y = mx + b form, do you know how to do that?

Best ResponseYou've already chosen the best response.2hm, I don't think A is one of the answers, let's walk it through step by step let's start with the original equation 5x + 4y = 8 we can rearrange this to get 4y = 5x + 8 y = (5/4)x + 2 the slope of the original equation is (5/4), so any line that is perpendicular will have a slope of (4/5) check each of the four answer choices to see which one(s) have a slope of 4/5
