You need to learn to define your terms when asking for help internationally. I've learned from your other questions that m in your country represents the x-intercept, not the slope as it means in America! Apparently your k means slope, and you've found the slopes of the given line and of the line through (2,3) and (4,0) to be 2/3 and -3/2, respectively.The goal was to determine the angle for which the line will have to rotate around a point (2,3) to have m=4.
I calculated that that angle is 90 degrees which is the correct answer, however, it also says alpha 1 = arc tan 1/7, why?
Tg is tan.
