Best ResponseYou've already chosen the best response.1Well, that's actually an expression, not an equation. An equation needs equal expressions, like\[y=3x14\]I assume that the angle you want to know is on the graph of \(y=3x14\). Does that seem right, so far?

Best ResponseYou've already chosen the best response.1Is this a question for class, or is it your own curiosity? I might have to research another way to get the angle than I had thought of using earlier.

Best ResponseYou've already chosen the best response.1And you don't know about the tangent a.k.a. \(tan\) function?

Best ResponseYou've already chosen the best response.1Well, I guess we might as well look at the graph.dw:1374722124721:dwI'm not sure which angle the question wants, but I assume it's the angle of the line measured from the xaxis and you would use the tangent function. Maybe I can find others to help us... With the tangent function, you use the equation \(tan^{1}(m)=\theta\) where \(m\) is your slope and \(\theta\) is its angle.

Best ResponseYou've already chosen the best response.1I would imagine you are, especially if you never used the tangent function! But I don't know any other way!

Best ResponseYou've already chosen the best response.1Ahhhhhh.... I seeee.... So, measuring, not calculating. I think I remember doing that before, too.

Best ResponseYou've already chosen the best response.0oh so instead of finding y you just measure from what x is?

Best ResponseYou've already chosen the best response.1So you'll need to have grid paper, so your line is straight and your axes are perpendicular and everything is accurate. Then you can measure the line accurately. Thank you, @Hero !

Best ResponseYou've already chosen the best response.1Sweet. Just set up the protractor along the \(x\)axis (or at least parallel to the \(x\)axis) and have that point on the line. Good luck :)
