The numbers closest to 0 are the ones that are "least" and the ones closest to 1 would be the "greatest", so it would go .41 - .46 - .60 If it helps think about the numbers from 0-100, like 41 is less then 46 and 46 is less then 60. :)

Since the lines are parallel this means the slopes are the same. You then use y2-y1 (slope formula) _____ x2-x1 and plug in both sets of points, (cross multipy) getting you 7(a-10)=-4(-2-a) 7a-70=8+4a 7a-4a=8+70 3a=78 a=26
