GRAPHING+LINES

__**Graphs of Linear Equations in Two Variables **__ //In order to solve and graph a linear equation, you must first put the equation into y = form ////. // y= -4 -x ** Then, using your graphing calculator, go to the Y= key, and type in the y= equation. Next, press 2nd Table an pick **at least 3 points** to plot. <span style="color: rgb(29, 160, 14)"> Graph all three ordered pairs on a coordinate plane and connect the dots using a ruler.
 * <span style="color: rgb(236, 113, 9)">x + y = -4

<span style="color: rgb(230, 124, 10)">**Any linear equation with only the //X variable// will graph as a //vertical line//. Any linear equation with only the //Y variable// will graph as a //horizontal line//.** If a point is on the x-axis, the y coordinate will be zero (x intercept). If a point is on the y-axis, the x coordinate will be zero (y intercept). __**<span style="font-family: Georgia,serif">Graphing Absolute Value **__
