Line J has a y-intercept of 9 and passes through point (a,b). What is the slope of Line J in terms of a and b?  Pick one.
A) (a−6)/b	B) (a−b)/6	C) (b-9)/a	D) (6−b)/a	E) (b−6)/a
You know that the line goes through point (a,b) and the y-intercept of 9 tells you that the line also goes through point (0,9).   slope m = (y-y1)/(x-x1) = (b-9)/(a-0)= (b-9)/a   (b-9)/a
