Question 1038318: The coordinates of the vertices of a scalene triangle (ABC) are A (0,0), B (3,3) and C (6, -6). The equation of a median from Vertex B is?
Is it x=3? But I'm quite confused when I'm getting the slope on the way to having an equation. If the slope is undefined, that means the answer is x=k, but what value will I use? The x-coordinate of the midpoint or x-coordinate of B? Thank you so much!

You can put this solution on YOUR website!
The median from B contains the point B (3,3) and the midpoint of A and C. That midpoint is the coordinates x=%280%2B6%29%2F2=3, y=%280%2B-6%29%2F2=-3. Now, the median of the triangle from point B (3,3) and the point (3,-3).

Two point for a line. Equation for the line? Are you trying to find the slope? Does this line have both a horizontal axis intercept and a vertical axis intercept? THINK!


...
The line is vertical.
highlight%28highlight_green%28x=3%29%29. That is it.
