PLEASE ANSWER I WILL GIVE U ALOOT OF POINTS

Answer 1

the answer is d 2 OK.

Answer 2

Solution:

Slope of line joining two points ,

$(x_{1},y_{1}) ,(x_{2},y_{2}) , is =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Take any two points that is , ordered pairs =(abscissa and Ordinate ), among four points given,suppose , (10,14) and (2,-2) or (2,-2) and (7,8).

$=\frac{14+2}{10-2}\\\\=\frac{16}{8}=2 {\text{or}}, \frac{8-(-2)}{7-2}\\\\=\frac{10}{5}=2$

So, if you choose any two distinct ordered pairs and find the slope between them using slope between two points , it will be equal to , 2.  

Option D: 2
