System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.

Expert Solution

Step 1:- Formula

Regression equation is given by,

Here X= Weight and Y= price

(A). Scatter plot

Correlation between X and Y is 0.

A scatterplot in which the points do not have a linear trend (either positive or negative) is called a zero correlation or a near-zero correlation
