if you are trying to find an angle and you only have this equation, 3x-14, how do you solve
Well, that's actually an expression, not an equation. An equation needs equal expressions, like\[y=3x-14\]I assume that the angle you want to know is on the graph of \(y=3x-14\). Does that seem right, so far?
Alright, now, have you learned trigonometric functions yet?
Is 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.
this is homework from summer
And you don't know about the tangent a.k.a. \(tan\) function?
Well, I guess we might as well look at the graph.|dw:1374722124721:dw|I'm not sure which angle the question wants, but I assume it's the angle of the line measured from the x-axis 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.
I would imagine you are, especially if you never used the tangent function! But I don't know any other way!
Alternatively you can just use a protractor and graph paper.
Ahhhhhh.... I seeee.... So, measuring, not calculating. I think I remember doing that before, too.
oh so instead of finding y you just measure from what x is?
So 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 !
Do you have grid paper and a protractor?
ya and i think i got it thank you @theEric
Sweet. 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 :)
