Find the equation of a line passing through the point (-1,2) and making an angle 13 degrees with the x-axis.
To be given this kind of question means that you must have learned that the slope of a line is equal to the tangent of the angle that the line makes with the x-axis.
so tan 13º = .2309
then y-2 = .2309(x+1)
take it from there
