You can put this solution on YOUR website!
This is just like y = 2x-3, which is a straight line. You can make a table of values and graph the points on an xy axis, or you can use the fact that the y intercept is the number term which is -3, and the slope is 2, which means $\"%28rise%29%2F%28run%29+=+2%2F1\"$ . See my lesson plans on graphing straight lines, especially with the slope intercept form of the line.\r
