Question

What is the slope of the line that contains the points (12, 17) and (-8, -17)?
Select one of the options below as your answer:

A.
0
B.
10/17
C.
17/10
D.
170/2

Answer 1

use the formula m= y2-y1/x2-x1

Answer 2

use point-slope formula
\[(y_2-y_1)=m(x_2-x_1)\] where (12,17) and (-8, -17) are (x1,y1) and (x2,y2)

that will tell you m (the slope)

then use \[(y-y_1)=m(x-x_1)\] and plug in your slope and one of the points
then solve for y
