Answer #1

Let us consider x=(1,2,3,4), y=(3,12,26,33)

Scatter plot between x & y is

Best line of fit is

From the above graph of best line fit, we can say (1,3) & (4,33) on the line of best fit.

The slope from the given data is 10.4.

I have done this problem in R. So, I am attaching the screenshot of my R-code
