In any given equation, a positive or negative number that isn't multiplied by a variable is called "b", or "y-intercept." Seeing as y-5 (f(x) is the same as y) isn't an equation, it probably means you need to add 5 to both sides to isolate y. you end up with y=5, a horizontal line in which every "y" value in every set of points is equal to 5 Ex: (1,5),(2,5),(3,5)... this means that your parent function of y=0 has a vertical shift upwards of five. hope I could help :)
She would earn $49.70 per day because $248.50 divided by the number of days (5) would equal $49.70 per day. You can check your work by working backwards. If she earned $49.70 each day for 5 days, she would have $248.50.
