Finding the Slope of a Linear Graph: Visual Analysis Method

To determine the slope of the line shown on the graph, we perform a visual analysis:

• We examine the orientation of the line from left to right.
• The red line starts at a higher point on the left and descends to a lower point on the right.
• This indicates a downward movement, which corresponds to a negative slope.

Therefore, by observing the direction of the line, we conclude that the slope of the function is negative. This positional evaluation confirms that the correct answer is negative slope.
