First of all, we need to know what a function is.
A function is a binary relation between two sets that
Y=4-7x
because it equals = -7
and
y= -5/4x + 2
because it equals = -5/4
For this case we have that, by definition, the medians of a triangle are the line segments that are drawn from a vertex to the midpoint of the opposite side of the vertex. The medians of a triangle are concurrent at a point.
If we look at the figure, we can discard triangles 3 and 4.
Also, by definition, the median divides the vertex angle into two equal angles.
Thus, the correct option is triangle 1.
Answer:
Triangle 1
