The main difference between an ogive and a frequency polygon is - An ogive is a plot of cumulative values while a frequency polygon is a plot of the values themselves. An ogive is also called the cumulative frequency graph. It is a curve which shows the cumulative frequency of a given set of data.
A frequency polygon displays class frequencies while an ogive displays cumulative frequencies.
Step-by-step explanation:
Frequency polygon: In the frequency polygon we need to connect the mid points of the class frequencies of the histogram.
Ogive: In ogive, we need to connect the cumulative frequencies against the corresponding class intervals by a free hand curve.
Therefore, the major difference between frequency polygon and ogive is "A frequency polygon displays class frequencies while an ogive displays cumulative frequencies."
x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.
