The Nutria is a type of rodent that is considered an invasive species in California. The population of Nutria in the Central Valley has been on the rise in recent years and they have been destroying crops, vegetation, and marshes. Their destruction has been recorded on the coastal areas of the state for many years. Below are the data of the number of sites where Nutria populations were found and the total number of acres of vegetation that were destroyed, in thousands of acres. The data are displayed in the table below. Number of Acres A. Display the data in a scatterplot. Destroyed (1,000s) 21.1 Sites 94 84 21.8 69 16.9 49 14.3 21 14.9 23 9.2 23 6.2 19 5.4 11 2.3 10 1,7 11 12 1.6 Number of Sites B. Describe the association in context. C. Determine the linear regression model (equation). Write the explanatory and response variables in context. D. Explain (in context) what the slope of the line means. E. Explain (in context) what the y-intercept of the line means. F. Compute r2 and explain the meaning in context. G. Calculate the residual for the year where 21 sites were found with Nutria.

Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These families appear commonly in the solution of differential equations. When a constant of integration is added, it is normally modified algebraically until it no longer replicates a plain linear transformation. The order of a differential equation depends on how many uncertain variables appear in the corresponding curve. The order of the differential equation acquired is two if two unknown variables exist in an equation belonging to this family.
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are real numbers and a is the horizontal coordinate and b is the vertical coordinate. This type of plane is called two-dimensional and it contains two perpendicular axes, the horizontal axis, and the vertical axis.
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) geometry was introduced by the Greek mathematician Euclid, and that is why it is called Euclidean geometry. Euclid explained this in his book named 'elements'. Euclid's method in Euclidean geometry involves handling a small group of innately captivate axioms and incorporating many of these other propositions. The elements written by Euclid are the fundamentals for the study of geometry from a modern mathematical perspective. Elements comprise Euclidean theories, postulates, axioms, construction, and mathematical proofs of propositions.
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
