1.1 Integers and Rational Numbers

9.2. Functions as Graphs www.ck12.org9.2 Functions as GraphsOnce a table has been created for a function, the next step is to visualize the relationship by graphing the coordinates(independent value, dependent value). In previous courses, you have learned how to plot ordered pairs on acoordinate plane. The first coordinate represents the horizontal distance from the origin (the point where the axesintersect). The second coordinate represents the vertical distance from the origin.To graph a coordinate point such as (4,2) we start at the origin.Because the first coordinate is positive four, we move 4 units to the right.From this location, since the second coordinate is positive two, we move 2 units up.Example 1: Plot the following coordinate points on the Cartesian plane.(a) (5, 3)(b) (-2, 6)(c) (3, -4)(d) (-5, -7)170
