Answer:
The answer is y=0.45x+3.5
Step-by-step explanation:
m=0.45
y=mx+b
y-y=m(x-x1)
y-48.5=0.45(x-100)
y-48.5=0.45x-45
+48.5 +48.5
y=0.45x+3.5
A unit rate is basically the same as a unit cost like for example if you buy 10 dogs for 1000 dollars total then its 1000/10 and each dog is $100. since its 100 for each dog its 100/1 so the unit cost is $100
When dividing fractions, we follow a rule called "Keep, change, flip"
Basically, you keep the first fraction the same, change the sign to a multiplication sign, and flip the second fraction.
2 = 2/1
7 * 1 + 6 = 13
2/1 * 7/13 = 14/13 = 1 1/13
2 divided by 1 6/7 = 1 1/13
3 3/5 = 18/5
2 1/4 = 9/4
18/5 * 4/9 = 72/45 = 8/5 = 1 3/5
3 3/5 divided by 2 1/4 = 1 3/5
4 1/2 = 9/2
2 3/8 = 19/8
9/2 * 8/19 = 72/38 = 36/19 = 1 17/19
4 1/2 divided by 2 3/8 = 1 17/19
