Best ResponseYou've already chosen the best response.3is the equation spose to be in point slope or slope intercept?

Best ResponseYou've already chosen the best response.0either way, the point is not on the line, the derivative of y=3arccos(x/2) is y'=3/(sqrt(4x^2)) subbing x=1 we get the slope we get the slope of sqrt(3)
