First you must find what 9.5 percent of 78 is. To do so, put 9.5 percent as a decimal (.095). Next, take this (.095) decimal and multiply it by 78 (this gives you 9.5 percent of 78). You will end up with the number 7.41. Since 78 is being increased by 9.5%, add 7.41 to 78 to get the final answer of 85.41. Therefore, when 78 is increased by 9.5%, you get 85.41 as a result.
Answer:

Answer:
-1
Step-by-step explanation:
Given a pair of points, we can find the slope from the following formula
m = (y2-y1)/(x2-x1)
= (0--4)/(-2-2)
= (0+4)/(-2-2)
= 4/-4
= -1
Answer:
right
