Math Problem Statement

Determine the relationship between the pair of lines.

Solution

The image asks to determine the relationship between the pair of lines shown in the graph.

From the graph:

  • One line (blue) is sloping upward, while the other line (orange) is sloping downward.
  • The blue line passes through the points (0,0) and (4,3).
  • The orange line passes through points (-4,1) and (0,0).

To determine the relationship between the lines, we need to analyze their slopes.

Step 1: Find the slope of the blue line

The slope (m) of a line is calculated as: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

For the blue line, using points (0, 0) and (4, 3): mblue=3040=34m_{\text{blue}} = \frac{3 - 0}{4 - 0} = \frac{3}{4}

Step 2: Find the slope of the orange line

Using the points (-4, 1) and (0, 0) for the orange line: morange=010(4)=14m_{\text{orange}} = \frac{0 - 1}{0 - (-4)} = \frac{-1}{4}

Step 3: Analyze the slopes

  • The blue line has a slope of 34\frac{3}{4}, which is positive.
  • The orange line has a slope of 14-\frac{1}{4}, which is negative.

Since the slopes are neither equal nor are they negative reciprocals of each other, the lines are neither parallel nor perpendicular. They simply intersect at one point (the origin).

Conclusion:

The relationship between the lines is that they are intersecting lines.

Here are some related questions for deeper understanding:

  1. What are the conditions for two lines to be parallel?
  2. How can you determine if two lines are perpendicular?
  3. What is the general equation of a line, and how is the slope related to it?
  4. How do you find the point of intersection between two lines algebraically?
  5. What are other methods for determining relationships between lines on a graph?

Tip: Always calculate and compare slopes to determine relationships like parallelism and perpendicularity between lines.
