Objectives. 1  Enter and format data in an Excel spreadsheet in a form appropriate for graphing. 2  Create a scatter plot from spreadsheet data. 3  Insert a linear regression line (trendline) into the scatter plot. 4  Use the slope/intercept formula for the regression line to calculate a x value for a known y value.hanging the Scatter Plot to a Line Graph. Instead of adding a curved regression line, all of the points of the titration data are connected with a smooth curve. With this approach, the curve is guaranteed to go through all of the data points. This is both good and bad.
Quick Answer. Pluto has a diameter of 1,430 miles, which is six times less than that of Earth. Pluto is smaller than the Earth's moon. In 2006, Pluto was stripped of its status as one of the Solar System's nine planets, and given a new label as the largest dwarf planet..
Surface of Pluto. Lying 30 to 50 times as far from the sun as Earth, Pluto's composition bears a greater resemblance to the rocky terrestrial planets than the gas giants that are its neighbors. The surface of the dwarf planet appears to be dominated by ices, with some rock mixed in.cientists can use Pluto's largest moon, Charon, which is close to the size of the dwarf planet and similar in composition, to study the surface of Pluto.
