In the xy-coordinate system, line k passes through points (-7m, 0) and (0, 3m). Which of the following is a possible equation of line k?
Select:
A) y = -7/3*x + 3m
B) y = 3/7*x - 7m
C) y = 7/3*x + 3m
D) y = 3/7*x + 3m
E) y = -3/7*x - 7m
The slope of the line is 3m/7m=3/7.   The y-intercept is 3m.   the equation of the line is: y = 3/7*x +3m   The answer is y = 3/7*x + 3m.
