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!

The median from B contains the point B (3,3) and the midpoint of A and C. That midpoint is the coordinates , . 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.
. That is it.
