Answer:
slope= 0
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
m= (-4-1),(6-1)
subtract the x1 and y1 which is -1--1 equal to 0
now same goes for x2/y2 we subtract them
which we end up getting 10
but because we have 0 whatever number we get it doesn't matter because at the end our answer will end up being 0.
