To provide an accurate response, I would typically need to see the graph you're referring to. Unfortunately, I can't view images or graphs. However, I can guide you on how to answer these questions based on common mathematical concepts related to triangles and slopes.
If you fill in the details, here's how you might approach each part:
a. Triangles ABC and CDE are called similar triangles (if they have the same shape but different sizes) or congruent triangles (if they have the same size and shape).
b. The slope of the line AE can be written as the change in y over the change in x (often represented as "rise over run" or mathematically as \( m = \frac{y_2 - y_1}{x_2 - x_1} \), where (x1, y1) and (x2, y2) are two points on the line).
c. This is a linear relationship (if the line is straight) or could refer to a direct proportion or*** inverse relationship*** depending on the context provided in the graph.
Please let me know any specifics from the graph, and I can assist you further!
