In the xy-coordinate system, line k passes through points (-4m, 0) and (0, 2m). Which of the following is a possible equation of line k?	Select the correct option:
A) y = -2x + 2m  B) y = 1/2*x - 4m  C) y = 2x + 2m  D) y = 1/2*x + 2m  E) y = -1/2*x - 5m
The slope of the line is 2m/4m=1/2.   The y-intercept is 2m.   the equation of the line is: y = 1/2*x +2m   The answer is y = 1/2*x + 2m.1/2*  +2=
