Answer 1

(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

Explanation:

To find the slope of a function, we use the formula:

`m=(y_(2)-y_(1))/(x_(2)-x_(1)) = (rise)/(run)` (rise/run)

1.
`m=(1-4)/(5-2) =-1` (negative slope)

2.
`m = (-3--3)/(-4-6) =0` (zero slope)

3.
`m = (2-5)/(-1-3) =(3)/(4) =0.75` (positive slope)

4.
`m=(-7-8)/(-7--7) =(-15)/(0) = ?` (undefined slope)
