Like the previous post pointed out, this equation is equivalent to y = 6.y = 6 is the equation that could be represented by a horizontal line (all the y-coordinates are 6) on a coordinate plane.I'm wondering if you mistyped the equation. Should it be y = 24 - 3x? In that case, the equation would be a "diagonal" line with a y intercept of (0,24) and a slope of -3/1.
