A vertical line has equation x = some constant, and a horizontal line has equation y = some constant. Slope intercept form of an equation looks like y = mx + b, but in a vertical line, the slope is zero, so really, you can think of it as y = b (where b is the y-intercept.) A vertical line equation can not really be written in slope intercept form per se, so you just write it as x = constant (which will be the x-intercept.)
