Points (1,1) and (1,4) lie on line k. What is the slope of the line that is parallele to k? A. 0 (B). -1 (C). 1 (D). Undefined
find what is the slope of the line k...let m be that slope... \[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
Which one is y 2 −y 1 x 2 −x 1
any of those two...its 1/0 that means Undefined... these lines are parallel to y axis..
Thanks i wopuld give you a million medals for always helping me but i can only give you 1 :)
