Answer:
D
Explanation:
the slope formula is y²-y¹/x²-x¹
so if we take a y², it could be 4.3 and a y¹ would be 4.7 since it is before that. 4.3-4.7 gives us -0.4
and then we take an x², it could be 30 and a x¹ would be 20 and if you subtract both of those you get 10.
now going back to our slope equator we already subtracted so now its time to divide. we decided-0.4/10 which gives us -0.04 which is the same as choice d! hope this helps:()
