1. Given tabulated data for two variables ( x and y ), use linear interpolation between two data points to estimate the value of one variable for a given value of the other. Sketch a plot of y versus x and use it to illustrate how and when linear interpolation can lead to significant errors in estimated values. 2.Given two points on a straight-line plot of y versus x , derive the expression for y . x .. Given tabulated data for x and y , fit a straight line by visual inspection.
