Notes

A relation can be described in: ordered pairs table of values words equation Ordered pairs are graphed on a grid that is made up of 2 perpendicular number lines The lines meet at a point called the origin (0,0) x-axis is horizontal, y-axis is vertical If there is a positive x-value- move right If there is a negative x-value- move left If there is a positive y-value- move up If there is a negative y-value- move down First find the x-value then the y-value. Plot the point where the 2 numbers intercept. The left side will be the x-axis, the right will be the y-axis When creating a table of values, the unit on the x-axis goes on the left side and the unit on the y-axis goes on the right side. Record the x-coordinates/values on the left side and the y-coordinates/values on the right side.
 * __Plotting points__**
 * __Reading Ordered Pairs from Graphs__**
 * 1) Read along the x-axis to identify the x-value
 * 2) Read along y-axis to identify the y-value
 * 3) Write the 2 values as an ordered pair (x,y)
 * __Table of Values__**

-make a table-substitute values of x (if given domain) to find corresponding values of y. -plot the ordered pair on a graph
 * __Linear Equations__**

-make a table of values that satisfies the eqation -graph the points using the table and the x and y values The domain on a table of values will be the values on the left side and the range will be the values on the right side. The domain on a graph will be the x-values and the range will be the y-values. For a word equation, first identify the x and y coordinates. The x-values will be the domain and the y-values will be the range.
