1. Which line is the flattest (or is less steep)? Why?

a.

To determine which line is the flattest or less steep, we need to compare the slopes of the lines. The slope of a line represents its steepness.

To calculate the slope of a line, we use the formula:

slope = (change in y) / (change in x)

Let's assume we have two lines, Line A and Line B. To find out which line is flatter or less steep, we need to compare the slopes of both lines.

1. Calculate the slope of Line A by selecting two points on the line and determining the change in y (vertical change) divided by the change in x (horizontal change).
- Let's consider two points on Line A, (x1, y1) and (x2, y2).
- Calculate the change in y: (y2 - y1)
- Calculate the change in x: (x2 - x1)
- Divide the change in y by the change in x to get the slope of Line A.

2. Calculate the slope of Line B following the same steps mentioned above.

3. Compare the slopes of Line A and Line B. The line with the smaller slope will be the flattest or less steep line.

By following these steps, you can determine which line is the flattest or less steep.
