determine if points are parallel perpendicular or neither .....(2,4)and (-1,-1)
parallel?
points cannot be parallel of perpendicular....only lines can be
Oh !! :)
the 2 numbers are points on a line in a graph. i could graph it , but they want us to do the equation instead
Then i thnk they are parallel?
i dont need a guess, i need someone who knows how to write the equation.
i am sure QED knows xD
show me the graph bcuz if u just give me two points u cannot conclude anything
You can plot the graph.......
they are perpendicular
i know this part, there is an equation to figure it out with out having to graph them. i need to know how to do the equation , find someone who knows how to do that........
(2,4) and (-1,-1) with (8,0) and (11,5)
ok what about those two pairs of points?....do you want to know if the lines are perp or parallel?
the equation will determine that
first two points yield y = (5/3) x + wtvr 2nd two points yield y = (5/3) x + other wtvr therefore, the two lines are parallel since they have the same slope
that is stranger, cuz when i actually put them on the graph they are perpendicular. how did you get thte y- yield ?
to find the slope of each pair of points, you need to do (change in y) over (change in x)....they both give 5/3
ok, now i am gonna sound like i am giving you a hard time, i dont understand what you mean by change in y and change in x
is that y2-y1/x2-x1 ?
have you learnt how to find the slope of a line?
yes it is what u wrote
ok, it is just the different terms everyone uses are different and confuse me......sorry
its ok
