Math Problem Statement

Determine the slopes of the original line and a perpendicular line based on the graph provided.

Solution

In this image, you are working on a problem related to parallel and perpendicular lines. The given line on the graph appears to have a negative slope, and you are required to find the slopes of the original and perpendicular lines.

Step-by-Step Solution:

  1. Determine the slope of the original line:

    • From the graph, we can see that the line is slanting downwards from left to right, which indicates a negative slope.
    • By counting the grid units, the line seems to drop by 1 unit (in the yy-axis) for every 1 unit it moves horizontally (in the xx-axis).
    • This suggests that the slope of the original line is 1-1.
  2. Calculate the perpendicular slope:

    • The slope of a line perpendicular to another is the negative reciprocal of the original slope.
    • If the original slope is 1-1, the negative reciprocal is: Perpendicular Slope=11=1\text{Perpendicular Slope} = \frac{1}{-1} = 1

Answer:

  • Original Slope: 1-1
  • Perpendicular Slope: 11

These are the values to input in the corresponding boxes for the original slope and the perpendicular slope.

Tip: Always remember, for perpendicular lines, their slopes multiply to give 1-1, unless one of the lines is vertical.
