(2,0) (2,6) (9,6) slope ? what a golden ? solve :)

Question

owlcoffee · Answer

first off you'll have to prove that the points are aligned.

owlcoffee · Answer

$$\left[\begin{matrix}x_a & y_a & 1 \ x_b & y_b & 1\ x_c & y_c & 1\end{matrix}\right]=0$$
That is the equation you can use to prove that three points are aligned.

solomonzelman · Answer

it seems like a (right) triangle....   not even a(n explicit) function.
maybe there is a typo in these points (idk)

owlcoffee · Answer

I don't know really, too little information.

solomonzelman · Answer

there is no slope here. well, only between the slope (of the secant) between the last 2 points

solomonzelman · Answer

hehe-:(

owlcoffee · Answer

Well yes and no, if the three points are aligned, the slope that represents the first two, must also represent the third.
