I was wondering if someone could check over these answers for me.
Find the slope between the set of given points:
a) (3,-6) & (-2,-7)=2.6
b) (7,5) & (7,-4) = -9
c) (0,-5) & (16,-5)= 16
I just wondered if the answers I have are right.
None are right
If you have two points in x,y format, say the two points are (a,c) and (b,d)
slope= changeY/changeX or (c-d)/(a-b)
