tamaranim1 [39]
y=\frac{1}{2}x+3 \parallel y=mx+b

Two lines are parallel when their slopes are the same.
m=\frac{1}{2} \\ y=\frac{1}{2}x+b \\ \\ (2,5) \\ x=2 \\ y=5 \\ \Downarrow \\
5=\frac{1}{2} \times 2 + b \\ 5=1+b \\ b=4 \\ \\ \boxed{y=\frac{1}{2}x+4}

How many whole servings of 3/4 cups are in 3 1/2 cups of ice cream?
Kisachek [45]
Well, what you're going to do is.. turn 3 1/2 into an irregular fraction.

3 = 6/2
we still have the initially 1/2 left so we will add that.
7/2

now we want to change it so that the denominator is equal to 4 so we multiply both top and bottom by 2

14/4

now we divide the 14 by 3 and you will get approximately 4. we will ignore the rest because it asks for whole servings and 3 only goes nicely into 14 4 times
