Slope Formula m = slope Algebraically Graphically

7
Identifying Slopes No Slope Positive Slope Negative Slope Zero Slope Undefined Slope

8
HOY-VUX No Slope Zero Slope Undefined Slope H - Horizontal Line 0 - zero slope Y - equation is y = (constant) V - Vertical Line U - Undefined slope X - equation is x = (constant)
