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.
The y-Variable
The data points would be .4 and .21
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.

The mode is the number of repeated data points. There is not a mode in the data you have given.

the average
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.
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.
extrapolate
(the number of data points between 5 and 12)/(the total number of data points)
