Answer:
For points : (2, 12) and (6, 11)
, option A. is correct.
For points : (6, –1) and (–3, –1), option B. is correct
Step-by-step explanation:
We are given points in both the questions and we need to find the slope.
Slope refers to steepness of curve .It is basically change in y with change in x.
For two points
, slope of line PQ is 
For points : (2, 12) and (6, 11)
Let
,
Slope is
i.e, - 1 over 4
So, option A. is correct.
For points : (6, –1) and (–3, –1)
Let 
Slope is
So, option B. is correct
