In my graph I have one line that decreases. What would be the shape name of a curve that would do so?

This question is not clearly stated.

Many shapes have lines that decrease and/or increase just the same.

A line that decreases reveals a decreasing function; a line that increases reveals an increasing function.

If you have a line that decreases in your graph, the shape name of a curve that would display a similar trend is called a "decreasing curve" or "downward-sloping curve."

To understand this better, here's how you can identify the shape name of a curve that would decrease:

1. Look for a downward slope: Check if the curve is generally moving from top to bottom on the graph. The line should have a negative slope, which means it is decreasing as it moves from left to right.

2. Observe the shape: If the line has a consistent downward slope, without any abrupt changes or irregularities, it can be classified as a decreasing curve.

Remember that an individual curve shape could have different names depending on the context or specific characteristics. For instance, a curve that consistently decreases at a decreasing rate is called a concave curve. On the other hand, a curve that decreases at an increasing rate is known as a convex curve.
