How do you get slope with no graph?
If you are given 2 data points, you can do (y1-y2)/(x1-x2) with the points. Given two intercepts, you can assume points based on the intercepts (if the x-intercept is 7, then one data point is (7,0). Then you can do the above once you do the same for the y-intercept.
When looking at data points on a given set of axes which variable is dependent?
The y-Variable
If you rent a car for one day and drive it for 100 miles the cost is 40 If you drive it 220 miles the cost is 46 What are the data points given?
The data points would be .4 and .21
What happens in the interpolation process?
Interpolation is a method of constructing new data points within the range of a discrete set of known data points. Basically it's a way of estimating certain values, based on information that is already given.
Given the data points 14 29 4 19 what equations describes of the best fit line?
= -1 + 5x

How do you show the work to get the mode of 34 41 37 29 33 35 43?
The mode is the number of repeated data points. There is not a mode in the data you have given.

What is the sum of all the data points divided by the number of data points?
the average
What is the difference of average and media?
Average is the sum of all data points divided by the number of data points. Median is the data point that is exactly halfway between the lowest and highest data points.
How do you solve range?
The range of a set of data points is merely subtracting the lowest number from the highest number given in that set. For example, a data set that contains the points 4 ,7, 9, 20, 6, and 11, has the range of 20 - 4, or 16.
When you extend a line beyond your data points to predict the value outside your data points you?
extrapolate
What fraction of the data is between 5 and 12?
(the number of data points between 5 and 12)/(the total number of data points)
What type of graph would be best for data points?
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
