Find the slope of the line containing the points P1 and P2:
P1(6, -4) P2(4, -2)
Find the slope of the line containing the points P1 and P2:
P1(6, -4) P2(4, -2)
To find the slope, it is the difference in y value and different in x value
-4 - ( -2) divided by 6 - 4
This is -2 over 2
which also is -1
I hope this helped,
