Slope Formula m = slope Algebraically Graphically

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

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)

Example: Find the slope of the line with endpoints A(-3,-1) and B(2,5) OR

Find the slope of the line with endpoints A (4,2) and B(7,2)

Find the slope of the line with endpoints A (-3,5) and B(-3,-1)

4. Find the value of k so that the slope of the line passing through the points (5,3) and (k,6) will be 1.

15. Draw a line with the given slope m that passes through the given point.
