We can find the midpoint of any line segment using the midpoint formula: M=(x1+x2/2,y1+y2/2). Essentially, the midpoint formula finds the average of two points. If we use B and the first point and C as the second, when we plug in our values we would have M=(5-4/2,9-5/2). This can be simplified to M=(1/2,4/2) or M=(1/2,2) which is the final answer.
I hope this helps.

Answer:
If a price doubles, then it increases by 100%
Step-by-step explanation:
To find the percent increase, use the percent increase formula below.
(New - Old)/Old * 100 = percent increase
You can choose any number to be the old number and you'll get the same answer. For this purpose, we'll use 65. This would make the new value 130.
(130 - 65)/65 * 100 = Percent Increase
65/65 * 100 = Percent Increase
100% = Percent Increase
