(a) Explanation Given: Refer to the figure provided in the textbook. Formula used: The general slope intercept equation passing through two points ( a , b ) and ( c , d ) is: ( y − b ) = ( d − b ) ( c − a ) ( x − a ) Calculation: Let the year 1999 could be write as 0 so that, the year 2009 would be 10. Therefore, the U.S public that favors gun control straight line passing through two points are ( 0 , 65 ) and ( 10 , 49 ) (b) To determine To calculate: The slope-intercept equation of the line that models the percentage of U.S public that against gun control after 1999, also round the value of the slope, m , to one decimal place. (c) To determine To calculate: The year at which the percentage of theU.S public that against gun control and U.S public that favors gun controlfor the models from part (a) y = − 1.6 x + 65 and (b) y = 1.5 x + 30 .

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…

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…

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) ge…

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.
