Question 74744
For the 2 points: (4,1) and (1,4) 
*[invoke slope 4, 1, 1, 4]
So the slope is m=-1




For the 2 points: (-3,-5) and (-1,-2)
*[invoke slope -3, -5, -1, -2]
So the slope is {{{m=3/2}}}




For the 2 points: (-7,-5) and (5, -6)
*[invoke slope -7, -5, 5, -6]
So the slope is {{{m=-1/12}}}
