X

X-is for X-Axis, the vertical angle in a graph. 

The X-axis intersects with the Y-axis, and Z-axis. The x and y axis form a cordinate plane which contains four sections. (Look Below) An x and y axis can come in + or forms. The sections in which the x and y axis come in are labled. I- cordinate 1 II- corinate 2 III-cordinate 3 IV- cordinate 4

X-intercept The x-coordinate of a point where a graph crosses the x- axis.

To find the //x//-intercept, set //y// = 0 and solve for //x//.

3//x// + 0 = 12 3//x// = 12 //x// = 12/3 //x// = 4 ||
 * ||  || 3//x// + 4( 0 ) = 12
