Question

can u help find the slope of the line that passes through the pair of points (-2,3)(-2,-3) for a friend

Answer 1

That line is vertical. Slope is not defined for vertical lines.

Answer 2

@bigdog92

Answer 3

1) the formula to find slope is y2-y1/x2-x1
2) the coordinate are (-2,3) and (-2,-3)
3) distinguish the x1,x2,y1,y2 points
4) (x1,y1) -> (-2,3) ......... (x2,y2) -> (-2,-3)
5) use the formula so it would look like -3-3/-2-(-2)
5) then it would be -6/0
6) whenever 0 is the denominator, you know that the slope is undefined

hope that helps :D
