learn this, it really helps
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.
so u have a zero slope....this means ur lines are horizontal...and a little tip * when u have horizontal lines, it means that ur y values will always be the same...so if 1 point is (-2,4), then ur other point is (3,4)...because ur y's will be the same
