Question

Find the slope of the line containing the given pair of points. If the line is undefined, state so. Please be sure to show all of your work.

(-1, -3) and (-1, -5)

Answer 1

\[m= (y _{1}-y _{2})/(x _{1}-x _{2})\] where x1 and x2 are x values and y1 and y2 are y values. Just make sure y1 and x1 are from the same point and x2 and y2 are from the same point

Answer 2

0,y ; slope = y/0

Answer 3

This means the line has an undefined slope

Answer 4

(-1, -3) and (-1, -5)
+1+3 +1+3
------- ------
0,0 0,-2 ; slope = y/x: -2/0

Answer 5

yep

Answer 6

thanks guys!! sooooooo much :)
