    1. The problem statement, all variables and given/known data

    find the equation of the line with the inclination 130 degrees going through point (0,2)

    2. Relevant equations

    3. The attempt at a solution

    baffled at how to start...

    What do you know about the equation of a line?

    Maybe drawing it 1st will give you an idea of what the equation should be.

    A line of inlcination 180[tex]\cdot[/tex] going through (0,2) would have the equation: y = 2

    What is the slope of the line?

    for the past two days, I couldn't enter this site...

    thanks, for the equation, this is all the information given...I assume it will be in a "y=mx+b" format, but I am not sure. also the slope has to be a 130 degree angle with the horizontal axis (I believe the x axis)...

    if it helps, the class is math analyst, which is the one before calculus...

    No, the "slope" of a line, in this sense, is NOT the angle it makes with the x-axis, it is the tangent of that angle. Now, how is that "slope" connected with y= mx+ b?
