Explanation Given Information: The equation is, y = − 2 x + 4 . Graph: Consider the provided equation, y = − 2 x + 4 . First determine the three ordered-pair solutions of the equation y = − 2 x + 4 .Choose any three values of x as: x = 0 , 1 , 2 . Write these values in the chart as: ( x , y ) ( 0 , ) ( 1 , ) ( 2 , ) Now, replace x with the assumed values and then solve for y . First substitute x = 0 in the equation y = − 2 x + 4 to calculate the value of y as: y = − 2 x + 4 = − 2 ( 0 ) + 4 = 0 + 4 = 4 Now substitute x = 1 in the equation y = − 2 x + 4 to calculate the value of y as: y = − 2 x + 4 = − 2 ( 1 ) + 4 = − 2 + 4 = 2 Finally, substitute x = 2 in the equation y = − 2 x + 4 to calculate the value of y as: y = − 2 x + 4 = − 2 ( 2 ) + 4

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
