The line with the equation B + 2a =0 coincides with the terminal site of an angle X in standard position in quadrant IV what is tangent X

Answer 1

IF you're graphing a on the horizontal axis, and B on the vertical, then in standard form the equation becomes B=-2a, with slope -2 and through the origin. the line goes down 2 units for every increase of 1 by a

tangent of X = the slope of the line = -2

IF you were instead graphing B on the horizontal axis and a on the vertical, the equation of the line would become a=-(1/2)B with slope = -1/2 = tanx
