Answer:
The slope of segment AC is -0.4
Explanation:
We are given a figure of a bigger triangle ABC with a smaller triangle BDE within it. The slope of the mid segment of the bigger triangle ABC is given by DE which is -0.4.
We are to determine the slope of the segment AC.
Since the side lengths of these two triangles are proportional, the two line segments DE and AC are also parallel and parallel line have equal slope.
Therefore, the slope of segment of AC is also -0.4.
