Answer:
(2,4) and (5,1) --> negative slope
(6,-3) and (-6, -3) --> zero slope
(3,5) and (-1,2) --> positive slope
(-7,8) and (-7,0) --> undefined slope
Step-by-step explanation:
To find the slope of a function, we use the formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{rise}{run}[/tex] (rise/run)
1. [tex]m=\frac{1-4}{5-2} =-1[/tex] (negative slope)
2. [tex]m = \frac{-3--3}{-4-6} =0[/tex] (zero slope)
3. [tex]m = \frac{2-5}{-1-3} =\frac{3}{4} =0.75[/tex] (positive slope)
4. [tex]m=\frac{-7-8}{-7--7} =\frac{-15}{0} = ?[/tex] (undefined slope)
